I guess I shouldn't let it bother me, but another Lemming called me a mutt and insinuated I was trash for being Irish by dna

All I did was mention that I was mostly Scottish and Irish by dna. I didn’t even mention being part English and Welsh, too. Another reader saw my comment and decided to call me a “mutt” for being born in America. He also tried to insinuate I was worth less than him because he says he is English by dna. It really bothers me when someone reaches out to bully a stranger online, assuming he is superior to that other user. I added a screenshot so people can see one of the supremacy comments this guy made.

I’d honestly like to meet this person and see what he looks like. I’m curious to know the face behind the supremacy act on this guy.
