Is that really the argument? Or is the argument more "it really doesn't hurt anybody else so why care?"
You have a good point, I think between the two arguments, it covers 99.9% of how "they" feel (gee it feels bad to say They about Doc, but you guys know I'm only talking in context, here, and with respect).
To the "it's not normal" crowd, they have preached the scientific basis. To the "it's wrong", they have preached the "it's not hurting anyone else, so why regulate or even eschew it in society". Their stronger argument varies depending on the audience.
And truly, those are compelling arguments to many people. 1) Science backs up that it is, at least part, biological, and 2) Who does it hurt.
Well I could preach a 50-page sermon book on who it hurts, but why go there, I've posted many times before and there are myriad of studies that easily show people, for anyone willing to see, just how traditional nuclear families are the way to go and make 99% of all good-life metrics, about 99% more likely. There are always exceptions, yes, certainly there are the happy, stable, well heeled, faithful gay couples, I'm not saying there aren't. But anyone who has been alive for more than 3 weeks knows full well what is the general 'sex and romance' scene between homo versus hetero sexual people. One is about 10x more wild and chaotic than the other, and I think we all know without me going into the various practical dangers of that.
No matter who may say what about me, and how imperfect and flawed I may be (and am, I'm sure) as a human being and a Christian, I still believe that God meant a man to be with a woman, for life, barring certain extreme cases where marriages must terminate.
I see society trying hard to prove that wrong, and failing miserably, by a million metrics both religious and secular but widely visible to all.
I am not unsympathetic at all to a man who wakes up and feels attracted to another man. As I have stated many times before, the mere feeling or desire is not "wrong" - it can't be, any more than it is wrong for me to be conscious of the fact that the pastor's wife is gorgeous (and in case you're wondering, she is). It's all about what happens from there, of course, is where the rubber meets the road. Those men should be welcome into churches and communities exactly identical to everyone else - including the people still struggling with Rage, Jealousy, Dishonesty, Adultery, Lust, general Meanness or
any other wrong. However, that church or community should be under no "unwritten rule" that the gay man's struggle must be embraced as not-a-struggle, or right or good, any more than they should be expected to wear tshirts celebrating anger, jealously, dishonesty, abuse, lust, or any other wrong. There's a huge difference between accepting the person with love, versus celebrating their struggle with wrongs as if it were not wrongs. Despite it being long out of vogue, I'm still a fan of the saying "love the sinner, hate the sin".
It's possible to do that correctly, although the vast majority of Christians have not done that correctly and thus deserve the frustration vented upon them by the secular world.
While society has done a VERY good job of convincing most that trying to become "un-gay" is a no-go, and proposes many studies to "prove" it, I lean on some of what Doc has posted to question that. What society tells you is normal, or abnormal, or possible, or impossible, will have MUCH to do with a self-fulfilling prophesy. I believe if you could create a magic "go back in time" situation to the 1950's, and you could interview 1000 people who got counseling from a trusted Christian friend about homosexual feelings, you might find that actually, quite a number of them successfully got out of it and were happily married. But of course, that's hard to find now, since 1) in many jurisdictions the mere counseling would be outlawed, and 2) few are those who would seek the counseling with an open heart and without the current baggage of being told
all their life non-stop that there was no point in trying. Also, I'll admit it could be true that the majority of "un-gaying counseling" may have been done in the worst possible ways. There are different ways to do things, some hammer the person with a moral club and some may take a holistic and compassionate approach - don't throw the baby out with the bathwater, despite what a tiny baby may have been in a large tub.
Trust me, if I was raised from the time of infancy to believe that every time I saw a gorgeous woman I simply must drool and sometimes pounce, I'm totally positive that I would believe there was no going back, and that any attempt I made to counsel myself out of that drive would result in complete and abject failure (enter the 'studies to prove' concept) - but would those studies be TRUE? Not really, they'd be based on everything I'd been told all my life. The position of your heart and what you believe is possible is everything.
Add to that the fact that nobody who has actually been through this will speak up if it goes positive, because that's too embarrassing for them at that point. The only people who will speak up for statistic-counting-purposes will be those who "I tried it and it was horrible, and eventually I accepted it and now I'm happier" - well of course you're going to get studies saying it's 0% possible. This all seems obvious in a way...
