"Every bit of censorship can be argued to be censoring dangerous lies."

This. Former Czechoslovak Socialist Republic and its secret police (StB) did not say "we are evil and we want to suppress information that contradicts whatever we need you to believe". It was a necessary struggle against Western ideodiversional centrals that were sowing lies among naive young population for nefarious purposes, of course.

Every censorship system will cloak itself in righteousness and necessity. Has been tried for hundreds of times. If anybody still accepts this argument at face value, they are likely ignorant of history.
