Nope. Altruism promotes ethnic homogeneity.
Altruistic people promote stable societies with high life quality. This setup encourages mixing, and as a RESULT the population becomes more homogeneous.
Selfish people punch down which promotes others to punch down, which reinforces social "caste" boundaries.
I actually think this is also the phenomenon behind some white ruralites being more decent-than-you'd-expect towards individual POC.
Just posted this because I always see chud pseuds parrot this and I've never seen it rebutted
Ivy, this is a nuclear grade bad take. You shouldn't accept the premise that people in "racially homogenous" societies are more altruistic. That's a) the opposite of what research suggests and nearly unfalsifiable as a general claim and b) carries whole aqueducts worth of water for fascists.
Accepting that probably false and near unfalsifiable premise means you're suddenly talking about "racial homgeneity" as the major factor which affects how people in a society treat each other and presents the world through a fascist racial lens instead of a socialist class based or material lens.
