Is fine if you are not into some kinks. But don't you think is weird when people complain about even the mention of something they don't enjoy happening? I mean, Im not a fan of rape scenes, is quite the turn off for me, now would you think is reasonable to complain that part of the backstory of the MC involves rape? I mean of course it won't be something that I would be thrilled about, but if I don't have to see actual rapes happening is not (or at least it shouldn't be) a big deal, like at all.
In the end, of course, we are allowed to complain for whatever reason, is our god given right, but I think the adjective "wimp" is a valid descriptor for people who complain about things that are considered trivial for the other person, not because they should be into it, but because they aren't seeing anything and still get angry for the bare mention of it happening.
