Ugh, homogeneous population is overrated. When you remove axis of discrimination from humans they just go down a level or too and use that as the basis for prejudice.

There's no such thing as a "homogeneous population". https://en.wikipedia.org/wiki/Realistic_conflict_theory#Robb...

I don't have evidence to say that it is irrelevant, but people love using homogeneity as a cope for being unwilling to try things to improve the status quo. Hate this argument.

They were likely in a homogeneous population when they committed the crime that got them there in the first place, so that confounder might not matter much at all.

Yes, in the sense that higher social trust, enabled by homogeneity is helpful in many ways. Robert Putnam among others wrote about it; Putnam wrote “Bowling Alone”.
