Don't you think its a bit extreme to boycott a game because of a single devs views though?
Isn't this the same as those saying we should boycott Hogwarts due to JK Rowlings views/opinions?
I think both are as stupid as each other (not condoning either by the way, I don't need to like what either have said, but its their opinion). Your first point is the one that is the most valid, most devs just don't care about politics within large studios, those that do care about politics are in the (vocal) minority and we would like to think that they were employed due to their technical ability not due to their race, colour, gender, political leanings or personal opinions (I'm sure some of that does go on though to be clear).
I personally (mostly) separate art from artist unless the artist has done something extremely illegal, even then its personal choice (some musicians have committed murder yet their music is still listened to). I, for example, do not agree with the hypocritical views of David Draiman, but I am going to watch Disturbed in October, and can't wait to do so (I watched them live when Down with Sickness was released and this is the 25th Anniversary so seems like the perfect time to see them again but my missus has never seem them live and its one of her favourite bands, they are touring with Megadeth who, for some reason, I have never seen live so bonus for me
