I see a lot of hypocrisy from the left on this issue. When their mobs attack someone, they say that if you express an opinion, other people have the right to criticize you for it. But when the left are attacked by mobs, they describe the actions of the mobs as harassment, and either get the law involved, eg through restraining orders, or lobby for more laws. The ambiguous nature of these laws, both existing and proposed, encourage this double standard.
