You should use that since in the previous post above you said there is no proof that there is or that there isn't. There was no point in you even replying if that was the case. Let me ask you this question. You said that homosexuality is normal and should not be considered a mental illness, you provided a theory on how mother nature is taking it's course and breeding out more homosexuals so we won't overpopulate the earth, if all this is true, then wouldn't grown men be attracted to children be normal as well because children can't reproduce? Wouldn't mother nature also produce more of these to stop us from overpopulating the earth?
Bottom line. Homosexuality is a mental illness. If you don't want to consider it a mental illness, don't consider people who like little children and who fuck animals to be mentally ill. You can't have one without having the other.
