God does not appear to mind gays. Otherwise, why would he allow so many of them? Could it be some sort of a clever test to temp straight folks (with their guard lowered by a few beers)?
What makes you think God interfers with our free will? You could ask the same question of Muslims or terrorists or even armies following your logic.
If you do not think gay is a choice for at least some gays... you have not known enough gay people. What about all the bi sexuals... is that genetic too... no choice involved. If you know gay people you see a spectrum. Some struggle with their choices... some say they knew they were gay from the beginning.
