What restrictions on freedom of speech did mccarthyism lead to

McCarthy was a bigot. If he and his cronies didn't like what you had to say, you were hounded for un-American activities and suspected communism. Many entertainers fell foul of him and never worked again. He drove many to suicide and America became paranoid so most people said nothing to avoid these wild accusations from a fanatic. His departure was no loss to America and it was able to return to being a free country with ALL the freedoms.
