But there is no good side to rape, (except statutory rape, which we differentiate by name and isn't closely associated with rape). Whilst the worst of drug addiction, torture and killing equals the worst of rape, the lightest of rape is much much more scarring than the lightest forms of torture, drugs and killing
There are still many places where a man forcing his wife to have sex with them is considered ok, and the woman who refuses to have sex with their husband is vilified. It's not that long ago that things were like that in the countries like US, either.
Not to mention that people will disagree on what is rape, a disturbing amount of people consider it ok to pressure someone into sex.
I'm definitely not saying they are right, but since your point was that unlike something like killing, rape is universally opposed, I felt like pointing that out.
I don't think TvTropes should remove the content, but they should keep the pages better moderated. It's not just fetishist stuff, a lot of pages don't have much value, apart from reading stuff about things you have already seen. They tend to be so cluttered with non-important trivia (In episode 5 of season 8 one of the characters tells this kind of a joke) finding for example what series focus on certain themes can be difficult.
But I guess removing stuff is just the easy solution.
