Just go look at your average thread and see what happens when someone dares speak heresy. Pouting, give it a rest. This place is enforced by folks like you who will go to any lengths to make sure your side is the only one heard. Try disagreeing with one of your "friends" and see how open they are to dissension. But yeah go ahead and dismiss it as this turns into the Conservative version of DU. You don't need Bushbots anyway. After all we're "retarded".

Again, not being listened to is not the same as not being allowed to speak. And the actions of many Miers supporters in this thread is akin to a kid striking out in Little League baseball dropping his head, saying "I hate this stupid game", taking his ball and going home to complain how the umpires hated him, his teammates didn't like him, etc.
No one was denied a right to speak on here. Some arguments weren't as compelling as others, as is always the case. Until you find that your posts are routinely removed by moderators, you're not at DU. So I'll state it again: The ability to speak your mind in here is not a guarantee that you'll have others agree with you.
