Being gay isn't natural?

It isn't at all! Our bodies weren't made for it. Why does everyone think it's okay?
Update: And why do they have gay pride parades? If we have straight pride parades, everyone gets upset.
Update 2: The same genes that produce homosexuality in men cause fertility in women.

The article only said that it might. One of the researchers also said, "We're still working on lesbianism, but were not getting to the same result, and possibly we'll come out with a completely different explanation,"
Update 3: To Cobalt:

Air conditioning and other stuff may not be natural, but it is useful. Homosexuality serves no purpose.
