I absolutely do not care what other people do in their private space. That doesn't affect me at all.
But what about the cases in which they want to express their sexuality in the open? Even I don't have any problem with the gays and lesbians, if they want to limit their love-making in the private. But I strongly object to the gay pride parades and other public displays, as I find them to be too repulsive and unsuitable for minor children.
