Feminism succeeded as far as it did because it managed to successfully appeal to Id level desires, which was free sex and "more money" and "justice against evil." That was what the three main "waves" in broad terms aimed for. More sex, more people working theoretically making everyone richer, and then punishing evil men who hurt women. All stuff that appeals to use on emotional cavemen level.

Now we all know that's mostly bullshit and the lies and consequences of it, but that's another essay.

Point being, these things can only succeed on a perfect scale as long as it has an instinctual appeal. It doesn't need a logical or proper framework, just the ability to arouse emotions in us towards it. Without those, you get something like the LGBT movement that needed government force just to get marriage legal because no matter how hard they try people keep rejecting it the moment they can out of disgust.

Cucking is no different. It arouses complete disgust in most men, to a point where I've seen men argue they'd rather be butt raped than cucked. As long as those base feelings remain, it'll never succeed and the men who do fall for it will be shamed into oblivion.
