The animal cannot give consent as two adults can.
Do you mean legal consent or actual consent? It is clear that animals can give actual consent because there exists in the world numerous examples of beastiality porn in which this is clearly true.
If you are referring to legal consent, prior to the 1973, Homosexuals couldn't give legal consent either. They were legally adjudged to be "non compos mentis" and therefore unable to give legal consent.
My point here is that your point is merely a technicality, and one which Homosexuals have overcome. Therefore it is not unreasonable to believe that beastophiles will also be capable of overcoming this silly technicality eventually. Indeed, in several other countries, Beastiality is legal.
No homosexual I know has ever said bestiality or child sex is ok.
Which proves exactly what? It is quite possible they wouldn't tell you the truth about these things because they know how normal people will react. If you go undercover in the "gay" community, you find out pretty quickly that they often make jokes about child molestation, and there is a lot of "wink wink" about it in those circles.
I've read reports and seen videos of homosexuals admitting that it is a common thing in the gay community to talk about "Chickens." (Young boys) Just look up
"Chicken Hawk" in the gay context and you'll see.
Beyond that, we have so many examples of prominent homosexuals molesting boys, of which Dennis Hastert is but one relatively recent example.
