For me the greatest concern of a censorship mechanism is that it blatantly encourages NPOV violation as common practice.
"Censorship" is of course a heavily loaded word, but I've never viewed content-tagging mechanisms, or "hide" mechanisms that are positively *un*hidden by default, as censorship.
(But yes, were such mechanisms in place, I suppose epic POV battles would be bound to erupt around the question of whether to use them in particular cases, immaterial though the outcome would be to the majority of readers who browse using default settings.)
