Speaking as a Christian who is pro-gay rights, I can say not all are, but yes, it's a subject that comes up too often. I cringe whenever it becomes the topic of conversation among other Christians I know. I think there are a lot of reasons for it. 1.) To someone who hasn't experienced what it's like to have any homosexual thoughts or temptation, they can't understand why people do it and it seems so unnatural and "gross" because that's how they would feel if THEY did it and they think everyone is the same deep down (hence, the its a choice argument) 2.) Because they fear that it's spreading like a disease. Over the last 50 years or so, more and more people are coming out. They don't get that there were always a lot of gay people, they think it's getting worse and that it could maybe spread to their own kids or something. 3.) They lobby against the legalization of gay marriage because they're all really afraid that the more WE - as a society as a whole - accept and tolerate "sin" then the more angry with US God gets as a nation... it might not be said out loud much, but there are a lot of biblical stories about entire populations making God mad and him just wiping them out. I think subconsciously Christians are afraid of that. 4.) There are many Christians who know it isn't a choice and doesn't have a cure, but believe perhaps that gay people are just given a bigger burden in life to bear and that those people are called to be abstinent. That being gay isn't a sin in and of itself, only "acting on it" is. 5.) A lot of people are just raised with hateful beliefs towards anybody "different" 6.) A lot of Christians are taught that it's such an abomination to God, that they really feel like they're helping a person by "pointing out their sin"... as if it's going to stop them from being gay and they would have saved the person's soul. It's sort of a mentality of, "I see you walking into traffic, I'm going to say something to stop you before its too late" ...they feel it's their duty to "correct" people. The problem with all of this is the lack of understanding of what their actions are actually doing - which is chasing people out of, and turning people into enemies of the church. Our message ABOVE ALL ELSE, is to love one another! And without understanding it's hard to create love. And if a person isn't willing to understand, they miss the whole point of everything.
