Language is an ambiguous and flexible thing, and a social agreement between the speakers.
We have to deal with it. We can criticise wording, but calling people and their wording fucking stupid isn’t going to help.
For me, as a European and a biologist, the use of the term “race” as by commenters in this topic is hard to bear. The usage in the US is very different from, e.g., Germany, Switzerland and Austria.
But I stop short of calling it bloody fucking stupid.
But enough of that. Back to the original claim: even if the poster above could provide enough evidence that othering and subsequent racism has a biological basis, we still - as others have pointed out - are able to transcend human biology as cultural beings.
Likewise, sadly, culture and society are able to de-humanise us.
