Actually I'm not going to tell someone whether or not they can or can't sleep with someone of the same gender. Who someone sleeps with has nothing to do with me and zero impact on my life.
I live by a strong set of morals, and I won't have a book written thousands of years ago, by people of that time that describes their understanding of the world, dictate how I will live my life. The bible is an absurd book to live by, and has so many interpretations and translations that it no longer reflects the original text anyway. And even if it did, the original text would have virtually no relevance to our lives today.
The key thing to understand is that religion is an invention of man. And our society grows and matures every day. So to continue to follow something that was designed to keep populations under control and reflect the understanding that man had of our world thousands of years ago is insane.
You won't agree with me of course and that's fine. You go be you.
