If you study the samples of homosexuality in mother nature, you may come to a similar conclusion as I have.

Ill use "the gay giraffe" as my example.

The gay giraffe, unlike us as humans, is free from the constraints of having any sort of contemplative abilities about his sexuality. The gay giraffe doesn't sit around wondering if what he is doing is "right or wrong", and other giraffes don't go around shoving their views about sexuality down his throat. Not even having to worry about what God thinks on the issue, we'll just say that by design this giraffe has been created perfect, in the context that he doing what his instincts and programming are telling him to do.

Moving on, Mr.GayGiraffe goes around having homo relations with other homo giraffes. He lives his life accordingly, just like his DNA is telling him to. However now, in spite of all of his "mating" behaviours, Mr.GayGiraffe and his "partners" utterly fail, and BY DESIGN thusly, to EVER produce any offspring.

Therefore, given all these parameters I have outlined, homosexuality is a natural mechanism for mother nature to kick your DNA out of the gene pool. Something in Mr.GarGiraffe is ultimately not good for his entire species, and now, mother nature is giving him the boot.

At least he can be happy that he got to exist at all and have buddies who he shared his time with, but thankfully for the good of all giraffes, he and his peers never pass on their DNA.

The end.
