And at the moment of writing it its front page has mostly has a few threads about MMORPG's, a Mario Kart 8 tournament, a Mario general and a thread about the Smash MGL. Yes, there will probably also be a thread about how awful anita is or EA being shit or whatever, so if it bothers you, you ignore it. That's the main rule of /v/ and if you don't like you're free to leave. I use it as a dumb humor site and for a few serious discussions around E3 time before going back to /co/ and /vg/, but I feel you're being completely disingenuous about how the board normally is just due to how anonymity naturally leads to some people being racist, sexist dickheads.
Even following your own logic about it being their most popular board you would realize not every discussion thread on /v/ is like that and the alarmist reaction GAF and other sites has to any mention of 4chan is part of why they get dumb and insular about so many different things. I'm glad I have GAF to talk about stuff like Feminist Frequency without being called a white knight or whatever (and I don't even fully agree with all of it), but I feel I'm mature enough to browse where I might see the "fag" tossed around more than once and not come out a worse person for it.
I just realized in the same thread I've felt the need to defend both GAF and /v/ while arguing the benefits of both, all over a giant postcard. Erm.
