Watching a new firestorm break out every day quickly grows exhausting. Same reason a bunch of people are getting sick of game performance threads, even if the overall subject merits discussion. Folks get wound up too much on both sides of the fence which makes the dialogue tiring to read for anyone with a moderate or undetermined stance, and then every possible point of contention gets blown into a new thread, so it's impossible to ever get them out of your peripheral awareness even if you're actively avoiding them.
This thread right here is entitled "Far Cry 4's art is racist", which is a very strong starting point for a discussion, and all the OP's got to back that claim up is Twitter reactions, which is the worst possible platform for constructive discourse. He's also not personally calling the art racist, so I can't fathom what he was thinking by phrasing the title in such a declarative way that's guaranteed to draw equally strong kneejerk replies.
Toning the ferocity and quantity of the discourse down would go a long way towards improving its quality.
Now here is a discussion we can have. I do agree with you that the OP doesn't help matters with his tone or his clickbait thread title. It seems to bring out the worst in people on each side, whether it be inflammatory titles with poor reasearch or the lamenting of adding diversity in video games.
The firestorms were enevitable, yet I expect nothing less. There are positives in creating some of these threads such as the Miiquality thread. If every thread was like that one, it wouldn't be Neogaf.
I don't really see the issue. Why can't a villain be gay, or flamboyant, or both? Why can't a light skinned character be racist, or just unpleasant towards a dark skinned character? Unless the writers are trying to suggest these things are good, or socially acceptable traits, what's the problem?
If we all put the disc in on launch day to find that the guy in the suit is actually the protagonist, and that the game is dedicated to glorifying violence and hatred against a particular racial group while spouting camp cliches, the OP might have a point.
