Your argument is that to get rid of people like WBC, the bad ones, we should get rid of all churches, even the good ones. To get rid of the whole to remove the bad, I understand that getting rid of a part of something sets a precedent that can be followed to get rid of the whole, such as a one denial of free speech could hypothetically lead to a complete abolishment of free speech, saying you can say everything but "x" may lead to not being aloud to say "y" then "z" so on and so forth, was that not what you meant? Unless I interpreted your words incorrectly that seems to be your point.
Please explain to me how that makes any sense at all in real life? That's an archaic black and white bullshit way of looking at things, do you really think that people are that stupid and that unable to realize how far is too far? There may be people like that but they are in the minority, most people know when to stop and when to keep going.
And I know that where the line is is unclear, seeing as how I said that, no one knows where the line is until it's crossed, and while yes, personal feeling do factor in heavily into it, the consensus between most people is that this particular group has gone too far. While strict adherence to the "everyone is created equally" and "all speech should be protected" are wonderfully idealistic, and in a perfect world are completely true, in real life most people realize that those things are bullshit, some people deserve to be treated differently and some people shouldn't be allowed to spew their vitriolic shit.
And I never claimed that celebration of death should be banned, what it comes down to is one group of people using their right to free speech to infringe on others' right to the pursuit of happiness, that is the problem with people like the WBC, they hide behind a right while infringing on the rights of others. The problem, at least in my mind, being that people look at everything too much in terms of either black and white, there are perfectly good grey areas that ought to be explored, my problem with your original statement is that you say "if you want to ban them ban all churches, else where do we draw the line?" we draw the line when we reach the line, we can form a consensus on where the line is, the majority can find and agree on a line.
