Why can't communist become citizens, but Nazis can?

Did you know that if you wanted to become a citizen, or a legal resident of the United States, you cannot be a member of a communist party. Not just a member of the Communist party of say, China (which we do a lot business with ironically) but even a communist party member here in the U.S.

Now, while it mentions communist parties, it does not mention the Nazi party, or other fascist parties. It does though mention a ban on those belonging to a "totalitarian party" but that is open to the interpetation of a government official. Also those who "write or publish subversive material" are prohibited. But, who determines what is subversive? Is subversive just simple dissent, if not, when does dissent become subversive?

Paul Robeson, an American who was born in New Jersey, was banned from traveling outside of the United States, for his advocacy of civil rights for African Americans, in the early 1950s. Indeed, he was told by the government, that "his frequent criticism of the treatment of blacks in the United States should not be aired in foreign countries—it was a `family affair." It didn't probably help Mr. Robeson that he was an advocate of communism.

This is hard to believe. In fact, I didn't know about this fact until I started doing basic research on this story. At one time, until a Supreme Court ruling in 1964, it was legal for our government to ban the movement of citizens to other nations because the government didn't like their speech. How is this any different than a giant Berlin Wall that forced East Germans and East Berliners to stay on one side of a wall? Well, it isn't.

I don't advocate communism, I am on the left, but definately not that far on the left. But, communists, like Nazis and every other group, have the right to advocate their beliefs. Including advocating them overseas. That not only people were banned because of communist beliefs but also because of their advocacy for civil rights, is downright amazing, let alone Orwellian.

Oh by the way, these anti-communists/anti-constitutional acts allowed for things such as arrests of those who protest outside courthouses, in trying to influence a jury. Jury nullification is acting on the fact that we have a right to not convict under unjust laws, in particular drug laws. That right predates even our nation, under common law.

If not for the courts, in particular the Supreme Court, we still might be barring not only communists but socialists or even Green party members, from leaving the U.S. Other rights, would be in a shamble. So whoever says the courts have too much power, is not someone whose own personal liberty is threatened. At least, for now.
