First he will go to jail because he is pedophile, not because he said something.
Now imagine if he isn't, but still say the most disgusting things to my child, i have all their right to protect her and report him for abusing a minor, by law.
But now imagine that he said the most disgusting things about me instead. As long as he doesn't threat me or do any defamation on me, i should not be be able to physically harm him because of that, and he should be allowed to say what ever he want by all the rights of free speech(does not include physical threats and defamation).
People should be able to deal with verbal abuse by themselves, not by law in this kind of situations.
