This is a hard question. My mother herself is a lesbian, and claims she has felt that way ever since a little girl. When I first realized what she was, it hurt, and I prayed and prayed she could change, but did not think it was possible.
Eventually Jesus proved me wrong, my mother says she still has those feelings, but can beat them now through her faith. I think being gay is similar to having a disability. It just so happens this disability prompts you to sin. We all have our cross to bear, and homosexuals or those that are "gender challenged" (I guess that's the PC term these days.) are not inherently evil, but bear the burden of having to fight their feelings, which is a far greater challenge than most of us have to deal with. That being said I also think its possible to "turn" if you embrace the sub-culture too much, or if you are exposed to it early on, as its prone to confuse a child about what their gender actually is, and what that entails.
What the real issue is, is that the media and the government are now imposing values which celebrate LGBTQ ideology, and they are doing so to our children. I don't understand why prayer is not allowed in school, but you can read kids stories about how little Jimmy has two daddies. Actually I do understand, but I think it's evil plain and simple.
If anyone is interested in this topic, there is a very very informative documentary about a man named Dr. Kinsey who is considered "the guru of sexology" (or w/e) he was active in the 40's and 60's I believe and was instrumental in the "sexual revolution" and normalizing alternative sexuality. He was also a correspondent with Aleister Crowley, Nazi's, and various sexual deviants, and was the person who laid the foundation for modern "sex-education". I won't get into too many details here, cause well they are pretty horrible and gruesome, but I assure you everything he did was documented by his own hand. For some reason people just don't seem to register the man responsible for normalizing alternative sexuality was well... A monster. If you look into Kinsey you will understand how our society got to where it is. I hope this was informative. God bless!
