(Just a clarification comrade - and I could be wrong, I’m doing this from memory - but I think the 100 million number is genocide across all of the western hemisphere from 1492. The figure I’ve seen for just what was contained the present USA is around 10 million. Doesn’t make it any less evil of course, death to America, but just wanted to clarify that for posterity)
I think you’re overthinking this. Literally just say “I’m a communist”, that’s gonna weed out pretty much everyone you wouldn’t want to get with anyway.
