"if genetic similarity is what's used to determine a social group all humans are one social group as there are genetic similarities between all humans. I'm not arguing against communalism or having no group identity, I'm arguing against genetics, having anything to do with a community or group identity."

I agree with the sentiment underneath these statements, but the logic is not sound. For instance, why can't genetic similarity, when used to determine a social group, be used for determining a social group that have geographical genetic similarities? Genetics can be traced back to geographic locations and populations. Why does it have to skip everything in between and only apply between ALL humans?

Honestly, it feels as if you have not actually presented an argument, your premises feel more like opinions and instead you've just stated that you are against genetics having anything to do with a community or group identity. A friend told me about this site and I just joined this night, so perhaps I'm missing some important information.

Furthermore, white nationalism does not necessarily have anything to do with genetics, I believe you are confusing it with white supremacy. While the same people may be labeled as both nationalists and supremacists, the two concepts are not the same.
