It's always OK for people to think what they want to think, provided they let everyone else have their own preferences and live in their own world.
Yes, the problems arise when people won't let those who believe and act differently from themselves, but do no objective harm to others, alone. And try to legislate their own religious values onto other people who do not share or want to be confined by those values.
In your case specifically Pfil I've said before and I'll say again that I don't find the idea of an all powerful all knowing God who created the universe compatible with bi or homosexuality being a sin, since God would have known you'd be gay the moment he created the universe and therefore chose to make you that way.
Granted, I used that freedom to get into some very sleazy horror/exploitation films in recent years but I've recently become convicted of that by the Holy Spirit and have weeded a lot of the more extreme movies out of my collection.
Don't think a supreme being would be that worried about what I had in my video collection personally. But different strokes for different folks, as long as it doesn't harm others do what makes ya happy.
