Jeez, can't we just save ourselves some trouble and just Ban Hitler apologists/deniers?

I was going to ask the same [slippery slope] question:

Shall we ban the following? Why, or why not?

  1. Moon landing hoax believers

  2. 9/11 thruthers

  3. Oswald did not kill Kennedy believers

  4. Global warming deniers

  5. Gun control opponents

  6. Republicans

  7. Fox News viewers
