There is a difference, a fairly large one I might add.
Yes, feeling sexual attraction is a part of human nature, but that doesn't mean that you have to act on those feelings, you have choice.
I'm not of that opinion, and we are not discussing our opinions on the matter right now either, we are talking about what is factually correct. And the facts are that you get punished for engaging in homosexual activities, not for just being homosexual. And yes, there is a difference.
