are you arguing that racism hasn’t changed at all since historical accounts of racism?

I mean, i don’t think i fundamentally disagree, but considering i was never talking about racism in the first place, im not sure how much this matters.

Speaking of ethnically relevant group social behaviors, china is a prime example of this. They have a certain type of behavior around foreigners, since they aren’t very common and chinese society is largely homogeneous, even including the existing minority racism that’s going on in china, those are more closely related to the broader populous than an american, for example.

you see similar things around other societies as well, this is extremely prominent among remote tribes and groups of people living in places the general populous doesn’t live. Interaction between the two is often, very weird.
