Your "free speech" does not trump my rights.
I don't believe you have a right to take away everyone's constitutional rights just because you want to feel safe.
When your "free speech" puts me (or even yourself) in danger you need to flip that > to .
The the very reason why many people oppose the TSA and Patriot Act is because it trades our privacy for (supposed) safety. Even if they kept us safe, I believe they are unacceptable because I think everyone's freedoms trump your 'right' to be safe from unlikely threats. Same with free speech.
Furthermore, with free speech zones, you're only talking about potential threats. Anyone who says something the president disagrees with is put elsewhere where they can't be seen or heard under the guise of keeping the peace. In reality, this is mere security theater.
There are countless valid constitutional arguments
I don't care what the supreme court says or does. No, that's not quite right. They can be wrong, and an example of that was when they allowed war protestors to be arrested due to the "fire in a crowded theater" ruling (later overturned, I believe). I believe very strongly in certain freedoms, and citing supreme court cases isn't going to change that. If that's all you've got to say, you might as well try to convince me that the TSA is a good thing; it'll be about as effective.
Further, Your "free speech" doesn't entitle you to live free on public land forcing the local tax payer to pay for your sanitation and protection and repairs for all damages done (both by squatting and out right vandalism).
You're too fixated on occupy wall street, I think. Free speech zones have been used for much more than that.
"Free speech" doesn't mean you can block traffic or block doors. "Free speech" doesn't mean you live rent free in a tent on public land. I'd bet cold hard cash that if me and 30 of my friends desided to protest your trampling of OUR rights by setting up a camp on your front lawn you'd have the cops on us before we got the first tent set up.
I'm done talking about Occupy. It's completely uninteresting to me and not at all the point I was making about free speech zones in general (which you apparently think are okay).
