Two consenting adults, including relatives?

It was only a matter of time before some Christian, stick firmly lodged in his anal cavity, came along and mentioned bestiality, a topic which Christians bring up so frequently in discussions like this that it makes you really wonder if it's the same game being played by the homophobic Christians who get caught soliciting blowjobs from other dudes in airport bathrooms.

I'd say the same goes for mentions of slippery slopes towards pedophilia, but we already know how the biggest sect of Christians handles that one.
