From what I understand they don't even care or find it funny, I mean why wouldn't they?
a) they're not an anti-gay group, their only real policy is Western chauvinism which is definitely right-wing but they justify it partially with the non-Western world's intolerance of gay people, i.e. the opposite of what this guy is claiming
b) due to the above they have a lot of gay guys in their ranks and even leadership
c) this is basically free advertising for their group and their membership has sky-rocketed (though that's probably more to do with Trump)
Genuinely don't get why Redditors can't disagree with someone without resorting to hysterical lies, there's plenty to criticise but I guess in a week we'll add this to the pile of failed Reddit slacktivism along with Activision and Hong Kong.
