Wrong. I did not assume you were a liberal democrat because you "don't buy the Al Qaeda connection." I don't think there's evidence to conclude that one way or the other. I made that assumption because you took a cheap shot at FR in general:
Gotta love FR, where the boogie man is lurking around every corner.
Remember that one?
Anyway, I never argued that the tape constituted "proof" of Al Qaeda involvement. In fact, I agree with your statement that it may or may not be a ME terrorist.
What I was arguing against was your seeming dismissal of the relevancy of this tape. The tape certainly isn't conclusive, but it certainly is relevant because it refutes one of the reasons you gave for this probably not being attributable to Al Qaeda:
Moreover, this pattern does not fit anything that al Q has done....they are in for shock value and big head counts....
The tape shows that Al Qaeda has trained in methods other than "big head counts", including random attacks on civilians and drive-bys. So your argument that "this argument doesn't fit anything that Al Qaeda has done" is made significantly weaker by the tape. That's why its relevant, and that's why your flippant dismissal of FR as a haven for people who believe in the boogie man was weak as well.
