The real irony is the American left were strong advocates of free speech in the 60s and now anti-First Amendment (ANTIFA) American leftists want to shred the First Amendment and censor speech they don't agree with. A real failure of the American education system to teach young people about how precious the American constitutional right to freedom of speech, even for unpopular thoughts and topics. 

If you really want government approved and controlled speech, move to North Korea or China.
