I don't think you have a good working definition of censorship. There is no authority figure here, and no one is being silenced; what's happening is people speaking up about things that make them feel hurt, threatened, and alienated. This is how things work in a free society.
It's great for that you've never felt subject to sexism. (Says in your profile you're in the UK, might have something to do with it-- I don't know if you've read anything about the political climate here in the States, it's a little actively hostile towards women right now.) But I'm afraid what you're saying is wishful thinking. The fact of the matter is some people are assholes, and it's quite possible to do your job well and still not be respected, and in our industry that falls much, much heavier on women.
There are fewer women in tech today than thirty years ago. We have a real problem, and ignoring it isn't helping anything.
