Facebook's censorship rules are sometimes incomprehensibly strict. Many women's accounts have been turned off for posting "men are scum".

Some men are scum, but not all. It is unfair to generalize that statement to all men. People should ideally know better than to be sloppy in generalization, even if they are justifiably angry at grave crimes.

However, is it right to gag people for unkind sloppiness like that? Clearly not.
