(God didn't create thieves, according to the scripture; they created themselves. That's not true with Homosexuality.)

Sure it is. Homosexual orientation or desire is not a sin. Never has been. It's the acting upon that desire that brings forth sin--just as desire for something isn't a sin, but when you act on that and steal something, that is sin.

Likewise, alcoholics are born with a genetic predisposition to abuse alcohol. Yet, we don't encourage them to just go with their desires when it comes to drinking, do we--even if it's what makes them happy?

It's not the temptation to non-marital sex that is the sin, according to Scripture. It is the mental and then physical assent to that temptation which leads to sin.
