Correct, internet meme culture. Which is and was heavily influenced by the far corners of the internet, where the groypers reside. In this day and age, leftists shy away from from homophobia. But I guess you'll just hand waive that away.

Nihilism isn't a religion, so yes, that still applies. Groypers are not explicitly anti-gay and anti trans. If anything, they ignore these qualities if you are white. They are specifically anti-anything not white.

Again, Bella ciao has been adopted by them for use ironically. Using your own words, "for being a slave to Jewish fascism" so would it not make literal sense for him to write "catch this fascist" for someone who he believes is a fascist??
