It IS. Thanks to idiots on *both* sides, including people on the right who haven't a clue how to combat the commie left and make the easy case against them before the American people, we are about to turn our country over to a bunch of 1960s pro-communist radicals. If you think that isn't serious, or is something we will easily be able to recover from, especially with Russia, China, Iran and Chavez all on the move, then you haven't a clue either.
It is true the rest of us also experienced the flaky symptoms and missing posts the past several days. I saw exactly the same as you said, only my own posts were missing from the thread. Several hours later they magically reappeared.
