Hate speech is free speech. I sure as hell don’t agree or condone any actions or thoughts from racist/sexist factions but I do defend their right to gather and speak because I don’t believe in censorship. Antifa violently protesting and trying to block any right wing supporter speaking at a college are doing exactly what their name is against. They are fascists trying to block and censor someone because they don’t agree with them.
What's "antifa"? Do you mean the anti-fascist movement that fought Hitler in WWII? Our heroes that stormed the beaches at Normandy? Those anti-fascists? Or are you referring to the bullshit republican propaganda?
From where I sit, the only ones trying to block and censor thought are those same republicans who are out there attacking those of us who oppose fascism. Are these, perhaps, the people to whom you are referring?
By the way, I served proudly for over 10 years in defense of our Constitution and all amendments to it including 1A which provides for our right to free speech. Protest peacefully. No problem here. After all, I am "antifa".
