You may feel justified in your censorship but you really are not free to redefine the word and punishing people for expressing unpopular opinions is censorship even if the people doing it like to pretend they are above such things. I know the left leaning folks tend to think that way but the sad thing is the left uses censorship at the drop of hat on almost any issue.

For your educational enrichment here is the wiki definition of censorship. Read it and then explain how this is different and please don't try and use a justification of censorship as an argument that censorship isn't taking place.

Censorship is the suppression of speech or other public communication which may be considered objectionable, harmful, sensitive, or inconvenient as determined by a government, media outlet, or other controlling body. It can be done by governments and private organizations or by individuals who engage in self-censorship. It occurs in a variety of different contexts including speech, books, music, films and other arts, the press, radio, television, and the Internet for a variety of reasons including national security, to control obscenity, child pornography, and hate speech, to protect children, to promote or restrict political or religious views, to prevent slander and libel, and to protect intellectual property. It may or may not be legal. Many countries provide strong protections against censorship by law, but none of these protections are absolute and it is frequently necessary to balance conflicting rights in order to determine what can and cannot be censored.
