Bestiality is more common than people would like to think as evidenced by the wide spread sex porn on the net of humans engaging copulation with subhuman animals. It's sick and revolting. Animals can't talk and report sexual assaults. If a person googles "dog sex", "horse sex" or even "bestiality" a million returns depicting human engaging sex with some kind of animal that even teenagers are accessing, downloading, and sharing with peer-to-peer software contributing to the delinquency of minors in all 50 States and animal cruelty. Committing crime and this corruption of minors is not part of free speech.
Freedom of speech becomes the rape, or assault and battery, instrument when porn, or torture recordings without or without sexual contact, are created and/or distributed, against one's will, or participant(s) unable to give legal consent; this includes acts of animal cruelty.
