Absolutely right on, hAppY giRl uNKnown! I really love what you said, "We need to stop being Christian and start being more like Christ." That's just super advice!
Yes, just as Jesus loved dearly all folks, especially those who "have gone astray" as-it-were (actually, haven't we all according to the prophet Isaiah, chapter 53, verse 6?), doesn't this certainly then involve tolerating the wayward manner of others? Who are we not to?
Therefore, let's put your advice into practice, and DO the things that Jesus did. DO creatively think of ways to meet some need of your gay or lesbian neighbor, and then offer your services (i.e., water their garden, tend to their pet, while their away on vacation). DO invite them over for dinner, even with his or her lover. If this idea rattles you a bit, then just consider him or her a friend, and treat him or her like one, just like anyone else that you would have some sort of association with in the world, such as at your place of employment! DO find commonalities in conversation that'll make them more apt to talk and laugh with you (i.e., movie and TV dramas and comedy, humorous events in one's family history). DO ask if there's anything that you could keep confidentially in prayer for them, that won't give them the idea that your trying to convert them on the spot!
It was these very things that attracted me to returning to the Lord and His people, after I had been in a gay lifestyle for a couple of years. Without experiencing these expressions of His love through those who represent Him, I don't think I'd be following Him, at least as diligently, as I am now thirty years later!
And, you are so right, contrary to what others have already said here, studies have shown that gays and lesbians are much more vulnerable to mental illness and substance abuse, and this doesn't seem to be directly related to the societal stressors of discrimination (yes, I've experienced this as well, and it's not a pleasant experience!). Rather, it is directly related somewhat to their unchosen affections, but predominantly so to their chosen lifestyles. (I'd be glad to get the professional journal reference for this fact, just in the asking, if you don't have it already.)
And, sadly, no, it is propaganda, not science, to say that people are born that way, and that they cannot experience freedom from these unchosen affections (Bailey and Pillard's identical twin studies from the 90's; Spitzer, 2002). Just like straight or bi sexually broken people, we gays and ex-gays can live a lifestyle of holiness and/or sexual wholeness in traditional bonds of marriage. And, no, the teenage suicide rate is NOT any higher than "straight" teenagers, according to science, nor has reparative therapy proven to be harmful. In fact, according to Jones and Yarhouse, 2007, it has proven to be beneficial to a majority of those who undergo such therapy, and is likened to the results and benefits of cognitive plus medication therapy for depressed clients!
