some people view censorship as an infringement of their rights, and, sometimes, they’re right.
some people see reasonable regulation of speech/behavior (especially in communal spaces) as a personal affront and a judgement of the views the hold and positions they espouse— often because their speech/behavior is seen as offensive and unacceptable by society. it reveals not only a deep insecurity, but a acknowledgement that even these people know, deep-down, that what they’re doing is unacceptable and wrong, and that their defense of it is disingenuous because their true motives are, in fact, malicious and hateful.
