Yep. You said it all. That alone should end the discussion, but I might as well throw in my two cents.
How can someone compare a private citizen's personal property with the action of a government in 1939? Ludicrous! It is censorship when the government stops you from speaking. It is NOT censorship when someone comes into my house as a guest and I ask them not to use foul language in front of my kids or whatever. These people are a bunch of complete idiots and give themselves away when they suggest that they believe we don't know who was behind the bombing.
