No, we want to let people be annoying, to a certain point. Otherwise we're really going to be trampling all over free speech.
For instance, people don't like a president. We want to let them go out with signs and express their view. They can't block traffic, they can't keep standing in your way and block your ability walk past, but that's a valid thing.
If someone is standing on a soap box and yelling, well you're free to walk past, or go to the other side of a street, or not even go down that street at all. If they're outside a business and the business doesn't like it, then they may have to relocate away from businesses, but we don't want to prevent someone from standing on a soap box. Remember the Russian protest area during the Olympics? We don't want the US society to become this:

If someone owns the sidewalk, then a person may have to go to the other side of the street to protest, and as long as they aren't impeding someone from going about their business, they're free to protest. If there are enough protesters, and the protesters are possibly crazy enough, then you have the potential for a riot and you may end up moving the protest area farther away, or only letting a few people protest at a time. Still, though, you don't want to crack down "too" hard on protesting, or expressing their viewpoint, no matter what it is.
Yeah, annoying people are annoying, but we don't want to try to legislate all annoyance out of existence.
Look, you want to stop the Westboro Baptist protesters? Set up a band right in front of them. They're free to line up outside a graveyard, the band lines up inside, right in front, and starts playing. After a few minutes of trumpets right in front of their faces, they'll move. "But funerals are supposed to be quiet." Look, do you want to hear hateful speech or some quiet classical music (presuming a funeral is held away in the middle of a graveyard)? 10 years from now, people might start talking about how you can't have a funeral without a jazz band.
