It isn't common now, but it will become so.<quoted text>No, no, no.
It will not come to humans and animals. Holy hell, people. What part of adult, mutual, and consent do you NOT understand??
Homosexuality is a sexual orientation. Being attracted to your sister is NOT. Desiring five wives is NOT. Those are completely different issues.

Jesus effin' Christ. If I was as scared of everything as you guys seem to be I'd just never leave the house.
And again, that dog humping someone's leg equals consent in someone's warped mind.
And what about a brother and sister that were separated and did not grow up together? How would they know not to be attracted to each other?
