Who decides? President Obama? Obama probably thinks you are a terrorist for visiting this site. You are far more trusting of politicians to make this distinction that I am.
He needs allies to take up his banner and rally around his simple but brilliant observation about the failure of the marxist crypto-muslim HUSSEIN BARAKAS socialist policies.
Of course, the President has the right to make that determination when it involves illegal combatants with whom we are at war. Why would he not; he is the Commander-in-Chief.
So far as Obama thinking we on this site are terrorists, Congress has not declared war on FreeRepublic. Not yet, anyway.
And I assure you that liberals will have no difficulty finding some kind of trumped-up legal reason to oppress whomever they choose. They'll do what they want, when they want, so long as the courts, the Congress and we let them.
Let's not confuse the legal exercise of power with the illegal abuse of power.
