So you're saying that people like this should be allowed to preach this wherever and whenever they want. You're saying that they should be able to get a license to start a radio station and broadcast this 24/7, uncensored. With the kind of money they make they could probably buy a few frequencies, and then it would be almost inescapable. Wow...
Yes. I am. Silencing them is one step toward fascism, one step away from our ideologies. They have the right to air their opinion, no matter how offensive. It's part of what makes this country great; Anyone can say what they want without fear of persecution like in the USSR or national socialist Germany. Yeah, I downright loving detest Westboro, I wish someone would mow them down with an Uzi, but the government has no right to stop them, and we have no right to demand their censorship. In China, speaking ill about the government gets you blackbagged, never to be seen again. It doesn't matter how loving offensive or ignorant something is, they have the right to say it regardless. Look at Glenn Beck, he says stupid bullstuff, and people listen - but we will not silence him because he has a right to say whatever the forget he wants.
The absolute ONLY exception is if the statement/words in question actually cause bodily or property harm, like shouting fire in a movie theater and people getting trampled, because that infringes on other people's rights.
