The problem you describe only concerns people who don't know anything about the subject, but still have no shame to have strong opinions about it.

Nobody in race sciences (anthropology, etc) claim that there are only unique races that are separate from each other and don't mix. This is a clear strawman.

The fact that there is mixing between races does not mean that races don't exist. You can make an emulsion out of water and oil, but water and oil still are their own things.

And the science has all kinds of specific categorization for human groups that go way beyond the rough separation into 3-4 main races. All the mixing, separation, migration, isolation, etc have been taken into account.

It's a pity this kind of topic/science is basically a taboo in the Western World and for real info and honest discussion have to go to other systems/countries/languages.

My example has nothing to do with race mixing lmao. Two Sub Saharan Africans today are literally descendants of people that never left the continent, there's no amount of 'race mixing' that would causing one of them to be genetically closer to another 'race' than to each other if race was a genetic reality. You're just an idiot with poor reading comprehension.

Between us, you are clearly the one with no clue about what he's talking about.

There’s more genetic variation within any so-called racial group than between groups, race mixing or not. Clearly, 'race' has no genetic justification.

You are only further proving my exact point.

You must be one of those clueless people who think that sex is fluid and is a social construct because there is in certain characteristics a bigger difference within each sex than between the medium of each sexes.
