some of the defenses along the lines of "eh its just video game culture, just heat of the moment,nothing racist we all say it" remind me of myself when I was younger and I used to say "that's gay" along with everyone else.
Then on message boards I saw arguements with people that took great offense to that term, at first my instinct was to be defensive, "it's not homophobic its just a synonym for that's stupid, i have no problem with gay people, I support gay marriage, you guys are just too sensitive, words change". Then I actually started to look at myself, grew up, and got some fucking empathy and realized I was being dumb as shit fuck up and yes contributing to homophobia. I've never used "that's gay" since, not in private, not anywhere.
these people like Pewdiepie and their defenders, they lack a certain empathetic center to "understand"(for lack of a better term, I'm being lazy) what they're doing is yes racist, hurtful and an indictment on their character, trolling is what's cool and funny, caring about anyone or anything? That's for oversenstive losers, care cup empty.
