Pantherman, have you never had any Gay friends or family that you have had the chance to socialize with?
I have, I have friends and family, and I can say as one christian to another, you can't be further from the truth. one man I know had some of his family basically abandoned him after he came out that he was Gay, do you think he chose that? no, he wanted his family to accept who he was, not a choice he had made, because no choice was made other then to be honest about who he was to not only himself but those around him, but they turned their back on him instead of embracing him for who he was.
A lot of Christians just do not understand the issue because it is not something that their safety net social group and family has learned to deal with or accept.
Most of their understanding of the Gay community only comes from people that share the same view point as themselves and from when they hear their preacher, preach against it in their church. usually not the best source of information to gardner an independent thought processes.
they all try to explain it away this or that way, but the most inconvenient truth of the matter is that they are born this way and from a christian understanding they cannot comprehend why their God would do such a thing, in their minds.
I finally convinced my devout Roman Catholic father of this. It was a long, drawn out process that took citing Biblical sources and introducing him to my gay friends. Although he never had a problem with gay people, he just thought it was a choice. My friends talked to him frankly and he came around. That's usually what it takes for most intelligent people.
