I guess by natural, I meant in the sense of nature. Homosexually CAN'T be natural since it goes against those very laws. Procreation....Male + Female = offspring.
And while its true that many, many animals commit homosexual/bisexual acts...it must be considered a sign of perversion...they simply want to 'get off'.
I can't believe that animals are emotional in the same way as humans...caring, loving, understanding are not reasons for two male monkey's humping. Not only that, but in nature, rape is really what's happening...as the dominent animal 'gets off' and leaves..
In the end, I think comparing humans to animals for this topic is really comparing apples and oranges...
