[Mali-]

I found the "we are not superhuman" bit annoying and condescending - replacing with different groups:

"While men are stronger than women on average, we are not superhuman" <- To me, this doesn't seem condescending. Not 100% sure why - perhaps because the difference in the trait (between men and women) is much larger?

"While left-leaning people are smarter than right-leaning on average, we're not superhuman" <- This definitely does seem condescending - perhaps because the skill in question is intelligence, and the statement reads as "You're stupider than me, but please strain your brain to understand".

"While rich people have higher IQ scores on average, we're not superhuman" <- I find this a bit less condescending than the previous one, not sure why. But still annoying for the same reason as previous.

"While whites are stronger than east asians on average, we're not superhuman" <- Again condescending and annoying, but I still think the intelligence statements are more grating.

My conclusion - the statement is irritating because it carries with it an implication people would be surprised Asian people can forget things too. Additionally, it gives the intention that because other groups are stupider, it needs spelling out in simple terms that they're not godly intellects.
