I'm not sure you actually know what "intelligent" means, b/c your argument certainly doesn't show it. You made a "faith based" argument. That is an argument based on what you fully believe to be true in the absence of scientific proof. I'm not prepared to argue your point from that perspective as I don't pretend to know the mind of God. But remember, that same book you are quoting also says that you can't go 6 miles from home on Sunday, You can't work on Sunday, you can't eat pork or shrimp, slaves should obey their masters, and that women should live outside the home during "that time of the month". How many of those have you violated?
On the other hand an "intelligent" argument is based on observation and scientific evidence. Longitudinal studies on this matter actually point toward the opposite of what you saying. So much so in fact that the American Medical Association has condemned "conversion therapy" as ineffective. The conclusion is that gay people are born that way, not made. Scientists estimate that about 6% of the population is homosexual. Interestingly enough, this is repeated in the animal kingdom as well.
