This is EXACTLY why it is limited. The moment anyone begins to so much as question anything done by the Bush administration, they are branded
ANTI-AMERICAN just as you have done. This isn't DIALOG, this is one-sidedness.
It isnt anti-American or unpatriotic to QUESTION the status quo, but there are many many vocal folks out there who seem to believe this, and there is no way that there would be discourse,only discord.
I doubt they would have banned it if people could have been civil, but that was not the case. There are many people who understand the 1st Amendment to mean THEY can say whatever they want, but anyone who disagrees must be shouted down and labelled.
To contain the inevitable flame wars, I don't see where they had any choice at all but to ban ALL such discussion.
