Block is a vague word, and I'm sorry for having used it given the number of replies that seem to think I condone censorship.

To be clear: any sort of physical violence, threats, or anything like that are not acceptable responses to speech. (I agree with everything you said after the first paragraph).

Nonviolent means of blocking, though — boycotting, (peaceful) protesting, writing letters, making calls — are totally legitimate means to block people from speaking at a certain venue.

Freedom of speech means that the government can't try to prevent you from saying anything. It doesn't grant you a time, place or means to say anything. Richard Spencer will find a place to speak. But it's in our best collective interest to all push him as far away from our own venues as we can.
