I wasn't arguing with you, clearly. I made a statement, then made a sarcastic remark. If I were to make a point, I'd say that this concept of "tolerance" that seems to be what you want everyone else to express, only goes one way, bud. If people disagree with people in the gay community, they are to be tolerant and respectful, but people in the gay community don't have to be tolerant or respectful of them.
There is a family in my hometown whose son was beaten within an inch of his life by a gay protest group. I don't believe gays should be bullied, disrespected, or denied public rights, but I reserve the right to disagree with them.
That being the case, I would say the other person's comment, though quite rude, was a blundering attempt to express the fact that they disagreed with the view presented in the photo. Obviously, it would have been better to have kept it to themselves, but they were in fact expressing an opinion, not intolerance (intolerance on their part, for example, would have been demanding the picture be removed for offending them). You, however, were expressing intolerance, by ordering them to leave deviantart because you believed what they said to be offensive.
Now I do hope you understand the difference between being offensive and being intolerant.
