I sure wish we could ban some of those assholes here. The Brits have sense.
So you think people expressing their beliefs should be a crime because you don't agree with those beliefs? This is exactly why we have a First Amendment, to protect unpopular speech. As long as these people aren't directly harming other people, they should have every right to believe what they want, hateful or otherwise. Nobody should be locked up for simply having membership in a group, regardless of how reprehensible their ideals might be.
