Pedophilia and sex with animals involves an adult with agency taking advantage of someone who cannot defend themselves and are not mature enough to make an informed decision. It is predatory.You shouldn’t have sex with animals or kids but some people want to do it. It’s what is accepted or not. Why can’t people remain celibate versus being deviant?
Sex between two consenting adults is a consensual act. This is nowhere close to the same thing. You might find it disgusting, but if they don’t why do you care? How is what they do with their bodies impacting your life at all?
Even worse, I’m guessing you voted for Trump who was found liable for literal sexual assault. But since he assaulted a woman I’m sure you are fine with it.
