Your post is obviously contradictory:

You write:

"It may be nearly Universal in animals, but should the same be applicapable, acceptable for Humans ?

Sorry, but IMHO , it isn't just about "nature". There are other issues like society, norms, values, religion etc which come into play.."

So on the one hand you say that in animals homosexuality is natural and commonplace, but that humans aren't animals so it shouldn't be natural within the human species.

Then you say that when it does occur in humans, it is for purely 'humanistic' reasons - ie as a result of social pressure or religion or whatever.

So it occurs in nature due to natural conditioning, but when it occurs in human beings it is as a result of totally non-natural causes???
