What is it about somebody not liking violence (especially sexual violence) in movies that sets so many people off?

EDIT PLEASE READ: This post is ten hours old so I'm not expecting many new comments in the morning but it is SO DISAPPOINTING how people missed the point so badly. I'm not wondering why rape is good or bad in movies. That is CLEARLY not the point! The point I'm asking here is why does criticizing that provoke such a violent reaction among men on LBXD? What about not liking rape makes somebody stupid?

TRIGGER WARNING: RAPE

This has been on my mind for months at this point, if not years.

A few years ago I watched "Once Upon a Time in America," directed by Sergio Leone. That movie's been on my mind for a while. One of the most ambitious, lengthy (4 hours!!) epics I've ever seen and it just did not hit for me. Some combination of it being overly long, boring, and a little disjointed made me not like it. It's all good. Probably a solid three-star movie for me.

What really stood out to me though is there are two really violent rapes in the movie, both by the main character. The movie shows the whole thing, twice. It's pretty clearly part of the character building in the movie, but I really didn't like them. Personally I don't have much history with rape (thank god) but it just felt really gross to me. I put it in my review and moved on, nobody really gave me shit about it. Just something I wish I didn't see.

Then I checked back on the movie a few months ago to see what changed and noticed a review I didn't see when I first watched the movie.

I won't link it, because I don't want to make it easy for people to give that author shit, since so many are already, but it's not hard to find anyway.

Her whole review is about the movie's treatment of women, especially with those two rapes. I think it's well written and a good perspective I didn't originally consider. 1.5 stars. Maybe a little harsh, but probably justified from her perspective.

But god damn! Something about this review must've ticked people off because it's got 120+ comments and most of them are people belittling her for feeling disgusted by a rape scene. I even commented and then within minutes a man responded to me going "but you're okay with murder?" I mean, fair point. But it's a weird as hell thing to respond, imo. Time and place.

The first negative comment explains:

I'm not quite sure you really got the point to this film. Especially when you talk about the rape scenes and bad lifestyles of the main characters. I'd be happy to explain why.

Then basically every comment after that for a while is some guy mansplaining about the point of the movie as if the reviewer didn't already clearly understand the point?

This peculiar idea you've acquired that the only interesting protagonists are morally correct ones, and that film isn't allowed to portray the often selfish, cruel, and senselessly violent aspect of humanity only reveals that you haven't matured past the mentality of a 4th grader

This one is wild to me, they aren't even saying that the protagonist would be interesting by being morally correct, they're just saying that they didn't like seeing so many women get abused, assaulted, raped, and murdered in the movie...

I mean, what the fuck is up with people?
