Cw are an optional way to help more people read your content, since the reader can prepare themselves before reading. I do not think people should be forced to cw things.
I do think it is ableist to characterize cw as censorship. For many of us the lack of a cw has the effects of censorship. We have to mute content we would have been able to read if we had a moment to prepare. It's okay to not cw, but please do not characterize the accomodation of our needs as something harmful or evil.
