why are there people who think rape is hot?

There just are people who like this. It's just part of their makeup that they get a sexual thrill out of hurting people. Why, nobody knows, it's just the way their brain is made. There is a whole S&M scene of people who enjoy this, sadists who like to inflict pain and masochists who like to receive it. But of course they will be sensible and avoid it going into the realms of being illegal. Or rather, as hurting anyone is illegal, the police tend to let it go if it causes no lasting harm and it's clearly their way of having fun.

Then you get the very few who can't keep it to play-acting - that accounts for most serial killers. That's nearly always a sexual thing, they love to torture, rape and take it to the final extreme of murder, and that kind of personality is described as a psychopath - someone who doesn't have feelings for other people.

Some people are simply faulty.

It's not normal to enjoy causing another person pain, suffering and brutal humiliation. Yet this is the exact atmosphere rapists often tend to enjoy. They probably wouldn't want to be raped themselves, but somehow think it's okay to perform atrocious acts upon an unfortunate.

Rapists are very cruel people and need to be removed from society, until they can be intensively taught how to control their violent impulses.

Most little millenial Snowflakes have NO idea that rape is incredibly violent and includes beating; very close to murder. It is NOT slap and tickle. And anyone who watches porn is a complete retard, because all of that is staged, plus people who watch that stuff are degenerates who are not capable of real relationships.

Fetish maybe. they like the rap because it tends people's love relationship and rap i wouldn't call it hot. i would say they like it but they just like it cause it's got good rhythm and stuff i guess.
