"I think nature gave us the inherent instinct to know that in-breeding is not conducive with self-preservation and can hardly be compared to homosexuality."
Oh? How do you know, just as with homosexuality? Do I smell a bigoted incestophobe? I hope I don't hear this term decades from now..
Since liberals tend to use animals as reasoning by stating that animals can perform homosexual acts, then why not also consider the fact that animals also engage in incestual acts?
Furthermore, homosexuality was a rare sin in the past, but now it's highly accepted as demoralization continues. Knowing this, I am sure incest will eventually be accepted as well. It takes a few, then a few more, then a few more, then a group, then a movement, then law changes/battles, then, well, people will most likely be debating this here as we are now with homosexuality.
Out of curiosity, wanting to test the validity of the previous statement, I searched a few phrases relating to incest on YouTube. Apparently, there ARE pro-incest people/vids out there. Hmm, is my theory totally impossible? I don't think so.
