I really don't understand some of the people here.
You can't punch people in the face or destroy property if you dislike them. Even if you call them Nazis.
You live in a democratic country. That's what laws and courts are for.
You are not allowed to take law into your own hands. That's not how it works.
If you feel so strongly about it, make sure the law changes to ban speakers like Milo.
Get people to vote. Get people to be involved in politics.
You cant just ignore the laws of you country because your favorite candidate lost the election.
Protest, write letters to media,senators or whatever you do in the USA. That's fine.
But advocating violence?
You are not living in Africa or the middle east (I am) where the governments can be corrupt or religious beyond repair. In that case I might have accepted "violence is the only way". But in the USA? No way.
I live in Israel. Here is a picture of a protest in Tel Aviv University against a lecture by an actual terrorist who served 4 years in prison for it (probably released due to some political deal):
That's how it's supposed to work in a democratic country.
And you guys are trying to defend using violence over a speech by Milo? That sounds insane to me.
