Why should gay people be expected to tolerant of anti gay views? Why respect people who think it's okay to discriminate against you? That's utterly stupid.
I would imagine that the gay percentage of posters on comicvine is quite high. Nearly every gay guy I know read comics at one point. Barely any straight guys I know have read comics. X-Men and Batman in particular have an established and massive gay following. I just stopped frequenting DC board because of the constant religious and anti gay views. I'd hate for comicvine to go down that route. Hate shouldn't be tolerated just because someone claims it's a part of their mainstream religion. It's just wrong.
As for Mann's art of course Gambit looks hot. Everyone in a Clay Mann book looks hot and actually healthy. Nothing is too exagerrated. Gambit was flirty(sleazy) in the tv series so people would have same associations with him as people would have with Catwoman. It makes sense to go this route.
