inferior races do practice incest, it is true.

most of the inferior races practice incest due to a culture of poverty. it is like prison politics where the same races stick together for survival.

england lost white power because the royalty had relations with family to keep noble blood lines pure.

mostly rich civilized white people who don't interbreed with family are the superior race today.

but if a rich civilized superior white person does have relations with a cousin f***er of an inferior race, they too will become inferior and lose their genetic evolution from diversity sex with descendants of white neanderthals.

lastly, poor whites do practice incest and become inferior like the other races from third world countries.
