Bob Nelson: “These people appear to be hardcore anti-American Communists …”

Let’s suppose — strictly for the sake of argument — that this is true. If it is true, what do you think follows from that about the FBI’s raids? Do you seriously mean to suggest that “hardcore anti-American Communists” should be raided, arrested and prosecuted for the government based solely on their political beliefs? If so, why? Shouldn’t people have a right to advocate any political beliefs they want, without fear of government intimidation or repression?
