I see afghans marrying out a lot on my fyp. As for chechens, they have problems and issues. I’d prefer they keep their abusive and savage manners to themselves. They need healing.Look Chechen people for example, they had a war with Russia which decimated half of their population which explain why they don’t marry outside, the same for Afghani people (not so much), war with USSR, thousands of muhadjin dead.
