What motivated this thread?
I think people are born homosexual or heterosexual but can exhibit behavior of the either orientation for various psychological reasons. I wish there weren't all the campaigns and insistence upon a monolithic "community" (a feeling not limited to this topic btw). When it comes to sexuality I don't think it necessary (I'm sure there is a better word) to indulge every errant thought one may or may not have. People should respect others but they do have the right to avoid associations they find unhealthy. Though I agree with xhonzi that it is better to have tolerance of those with different views. I've always been naturally tolerant (Warbler would be laughing were he able [a joke, Mr. Warbler]) and I find it unfortunate when people shun others for not being sufficiently supportive of their worldview.
