Are you kidding?
Don't compare black and white, they are not the same, even though they are both colors...
Okay, let me put it in a nutshell to make it clearer, pay attention.
Fetishes where everyone can consent to what happens are fine in general, and yes, there are some very strange ones, but everyone has their own tastes, but deviations where one part does not consent to what happens because they literally cannot, like in the case of animals or children who do not have the understanding, do not mature enough to consent.
If you tell me that a fetish like incest, where everyone is supposed to be an adult and consent to do what they do, is the same as a deviation like zoophilia and pedophilia.
Dude, I really have to think that you are joking because that is a very worrying thought if you are serious.
