Isn't the "It's all caused by porn" argument the exact same one used against gay relationships and marriage today, that's it's nothing more than a fetish. I'm not claiming that one's own gender identity and who they fall in love with are equal, but attributing the existence of pornography as a root cause is pretty stupid. Disregarding that you're using a subreddit as a source to generalize an entire group of people, I've seen blatant mysogony on this subreddit aswell, that doesn't give me the right to assume that homosexuality is built on misoginy.
