When people say "it's the natural way of life" - they haven't really researched it much.
Homosexuality is not only present in humans, but is present in many species within the animal kingdom. For example, penguins - there are a pair of male penguins who are raising a chick even!
Now, if you are looking at it from a psychology point of view - there are views that the difference between ourselves and animals is that we have a mind where as animals don't - that is - that we can think for ourselves, form opinions etc - animals don't. SO, if you look at the animal kingdom and find homosexuality which we've established you can - either its something that comes naturally, or if you are of the religious type - God created them that way - they do not have the excuse of sin, temptation etc etc.
How To Hub - actually, if you think about - Adam and Eve makes sense - in that you are trying to create a population - they can have reproductive sex. Errr...but if you look even further - it's all INCEST - which Leviticus forbids as well. Me thinks you between a rock and a hard place with the Adam and Eve arguement.
You also say - we believe we were created male and female - I don't believe that. So, please don't speak on my behalf - I am an adult, I can do that. So can all the rest of the world - so when you say something like that - "I believe" is the correct term.
