I usually prefer not to get too far away from MHRM here including issues of race, but this is a copy of a comment I made in a discussion here.

A diversity officer apparently tweeted "killallwhitemen" along with other disturbing behavior. We had common ground to oppose insensitive "PC" type thinking, and I prefer to avoid debates over race here but I wanted to reply to the claim that over the last 5,000 years, ""almost everything of significant value" was invented by white people. I recalled and found some interesting history if you have time to read it but it not, see the first two and last to paragraphs - and the idea we are stronger when we recognize we're all on the same side, for humanity and justice and equality and respect.

Key idea: Those who are about hate or disrespect whether towards Blacks or other minitories, or towards whites or men or anyone else, are on the other side. Those are the sides, not "whites" versus "others"

My post below:

I agree the media can be insensitive at best or entirely humiliating towards white people..And obviously the "killallwhitemen" is outrageous.

But, the idea that white people "invented almost everything of significant value over the last 5000 years" is quite an extreme statement, and no, I don't think it makes you a "racist" but I do think it hurts the cause we agree on (better media and cultural sensitivity) and I don't want to get into a big debate but here are a few links..

Just to help re-think the idea that "almost everything of significant value" was invented by white people in last 5,000 years:

1. The Wheel. Here it's a three way tie between Caucasus, Central European, and the not exactly white Mesopotamia

2. The huge invention of gunpowder. If that was the only non-white major invention, already we'd have to reconsider "almost everything of significant value"

3. paper "Paper was invented in ancient China during the Han dynasty (206 BC – 220 AD) and spread slowly to the west via the Silk Road. Papermaking and manufacturing in Europe was started by Muslims living on the Iberian Peninsula, (today's Portugal and Spain) and Sicily in the 10th century, and slowly spread to Italy and Southern France reaching Germany by 1400."

If these were the only two, plus the "tie" over the wheel, already we'd have to change "almost everything" to, maybe "most things" instead of "almost everything" But there's more.

4. And the Four_Great_Inventions

6. two inventions both woodblock printing and even movable type, were both invented in China:

The Chinese invention of Woodblock printing, at some point before the first dated book in 868 (the Diamond Sutra), produced the world's first print culture. According to A. Hyatt Mayor, curator at the Metropolitan Museum of Art, "it was the Chinese who really discovered the means of communication that was to dominate until our age."[28] Woodblock printing was better suited to Chinese characters than movable type, which the Chinese also invented, but which did not replace woodblock printing
Also Metal_movable_type_in_Korea was delayed, and still came out before Europe by a generation:
A potential solution to the linguistic and cultural bottleneck that held back movable type in Korea for two hundred years appeared in the early 15th century—a generation before Gutenberg would begin working on his own movable type invention in Europe—when King Sejong devised a simplified alphabet of 24 characters called Hangul for use by the common people
7. Our entire science uses the Hindu-Arabic numeration system, which arrived in Europe long after its invention:

976. The first Arabic numerals in Europe appeared in the Codex Vigilanus in the year 976.

1202. Fibonacci, an Italian mathematician who had studied in Béjaïa (Bougie), Algeria, promoted the Arabic numeral system in Europe with his book Liber Abaci, which was published in 1202.

1482. The system did not come into wide use in Europe, however, until the invention of printing. (See, for example, the 1482 Ptolemaeus map of the world printed by Lienhart Holle in Ulm, and other examples in the Gutenberg Museum in Mainz, Germany.)

1549. These are correct format and sequence of the “modern numbers” in titlepage of the Libro Intitulado Arithmetica Practica by Juan de Yciar, the Basque calligrapher and mathematician, Zaragoza 1549.
There is indirect evidence that the Indians developed a positional number system as early as the 1st century CE.[3] The Bakhshali manuscript (c. 3rd century BCE) uses a place value system with a dot to denote the zero, which is called shunya-sthAna, "empty-place", and the same symbol is also used in algebraic expressions for the unknown (as in the canonical x in modern algebra). However, the date of the Bakhshali manuscript is hard to establish, and has been the subject of considerable debate. However, no later than the 6th century:

" it is generally accepted that enumeration using the place-value system was in common use in India by the end of the 6th century.[10] Indian books dated to this period are able to denote numbers in the hundred thousands using a place value system.[11]

"In his seminal text of 499, Aryabhata devised a positional number system without a zero digit. He used the word "kha" for the zero position.[3] Evidence suggests that a dot had been used in earlier Indian manuscripts to denote an empty place in positional notation. [1]. ..The use of zero in these positional systems is the final step to the system of numerals we are familiar with today. The first inscription showing the use of zero which is dated and is not disputed by any historian is the inscription at Gwalior dated 933 in the Vikrama calendar (876 CE.).[3][12] Documents on copper plates, with the same small o in them, dated back as far as the 6th century AD, abound.[13]" The system was adopted by the Arabs who in turn introduced Europeans to it. Much better for science, business and commerce than Roman numerals.

The present Hindu Arabic system which is a positional
system, is what all our science stands on. "Before positional notation became standard, simple additive systems (sign-value notation) such as Roman Numerals were used, and accountants in ancient Rome and during the Middle Ages" had to resort to "the abacus or stone counters to do arithmetic.[2]"

Just found a link about algebra too. The words for algebra and algorithm come from this Persian fellow. While some of his writings were found to come from Indian and Greek earlier sources (so not just Greek but also Indian first time discoveries) he also invented some of his own:
J. J. O'Conner and E. F. Robertson wrote in the MacTutor History of Mathematics archive:

Perhaps one of the most significant advances made by Arabic mathematics began at this time with the work of al-Khwarizmi, namely the beginnings of algebra. It is important to understand just how significant this new idea was. It was a revolutionary move away from the Greek concept of mathematics which was essentially geometry. Algebra was a unifying theory which allowed rational numbers, irrational numbers, geometrical magnitudes, etc., to all be treated as "algebraic objects". It gave mathematics a whole new development path so much broader in concept to that which had existed before, and provided a vehicle for future development of the subject. Another important aspect of the introduction of algebraic ideas was that it allowed mathematics to be applied to itself in a way which had not happened before.[19]
