Since y'all are soooo fond of parsing down to the finest point about things, let's do this.
Antifa cannot deny you your First Amendment rights.
Only the Government can do that. Since the actual text is "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances."
See? The text says the government can't tell you to shut the f**k up.
Antifa, being a group of private citizens, have the right to tell facists to shut the f**k up.
Is violence the answer? Of course not.
And I'll answer the "so much for the tolerant left" bullshit that's gonna follow.
Being tolerant of ideas doesn't mean you have to tolerate hatred and bigotry. Racism, hatred, and bigotry have no place in a reasoned society.
It needs to be shown the door. And those who adhere to that ideology need to be told to shut the f**k up and get the f**k out.
