I am inclined to agree with Arc7Kuroi regarding that the image that AnimesFreak2 posted did not involve sex, drawings of underage characters, or even frontal nudity, nor was it posted in order to be offensive. I think that a warning instruction would have been sufficient. We cannot be too strict and totalitarian.
As for UltimateDarkGod666, he seems to have a repeating history of proudly outspoken homophobic sentiments, so I don't mind his ban.
I don't think that we should punish heterosexual men for finding lesbian couples attractive any more than we should punish women for being fans of yaoi manga though. It is an ultimately harmless fetish, and has nothing to do with hatred or intolerance.
Also, there genuinely do exist very reliable PEW Research comprehensive statistics surveys regarding that many Muslims and Christians are very uncomfortable with homosexuality. Other statistics show that they are quickly growing more tolerant in this area, particularly younger people, which is very good, but we cannot just systematically lie and pretend that this is not the case, and say that anybody who has read the statistics is somehow bigoted or has something personally against either homosexuals, Muslims, or Christians in general.
That said, UltimateDarkGod666 really did just use it as an excuse for being bigoted himself, which is anpther issue entirely.
