Freedom of speech to me, and at one time the Supreme Court, is the right to express any idea, thought or word that does not directly lead to harm. Period.

So you can say you hate Obama all you want. Go ahead, no one will arrest you.

But if you are somewhere in Obama's vicinity, you have a weapon, and you say "I'm going to kill Obama." then say goodbye to the 1st amendment.

There are NO topics which are out of bounds of 1st amendment protection. But please, remember, the 1st amendment is a protection from GOVERNMENTAL intervention, not private. The moderators of this, or any other forum, are incapable of violating your 1st amendment rights, because they aren't the Man.
