Who among us believes he had no idea what the Q movement was? He knew what kind of people they were (the kind that liked him) but didn't know anything else about it? Really?
Funny thing is, he could STILL shut it down with a word, especially considering its being used as 'the big lie' in the derps' power schemes.
So there's that.
