I'm assuming you mean that men are treated like animals by women and that this is why there is rape.
Why was there no similar epidemic when women were considered their father or husband's property? I can't think of a situation that would better fit the description of "being treated like animals" than that.
Sorry the past sucked. Luckily you get to live in the fanciful present, in a western democracy.
Your representative owes you, not his industry only, but his judgment; and he betrays, instead of serving you, if he sacrifices it to your opinion.
- Edmund Burke
When you treat people like animals, they frequently end up acting like them.
Respect is a two way street.
People don't generally rape because they were treated "like animals", tho one could argue that some people may become what they get accused of being as that wouldn't change their situation.
Most likely the person starts with a sense of entitlement, but is taught not to or afraid of public humiliation if they committed rape, they got dissed when they asked for sex and then their wounded ego felt the public humiliation they assume they'd feel if they'd just raped that girl, so they decide to become that rapist because no one would have sex with them when they were a good boy and respected boundaries and other people in general.
It's like the friend zone - there is no friend zone, there is just the "not my type" zone. Because yes, you can really like being around someone without wanting to have sex with them. People who scream about the friend zone feel entitled to the other person, like a rapist feels entitled to the other person's body.
A personal light example of this is how my mother used to grab my ass like she did to my father, when I pointed out what pedophilia was, she replied "but I am your mother", a response of entitlement, "I am entitled to do what I want with you, because I am your mother". More exactly it was sexual harassment, but I was underage at the time and sexual harassment of a minor is still pedophilia.
Point being, she did it because she felt entitled to it.
