The right to not be offended, quite simply, does not exist and should not exist in free democracies. Everything should be open for debate, discussion, parody, etc..
Not producing a movie because someone might feel insulted by it and then throw a temper tantrum is censorship by proxy in its purest form. The tyranny of sensibilities may be justified by humanitarian arguments (i.e.: "peace on Earth" !) but it is, more often than not, a disguise totalitarian doctrines take to silence opponents.
The fact that this attack allegedly comes from the last Stalinian regime - the worst dictatorship still in existence - certainly points to a totalitarian motive.
