For once I'm going to attempt to solve a WB riddle just to prove he's full of malarkey.
Here are all of Keller's posts regarding this up until WB made his initial "that wasn't what Keller said" post.

He very heavily implied this one other time.
He mentioned conservatives twice; once when referring to the title of this thread and again when saying conservatives can't read.

Okay I got nothing. Can I at least use my 50/50 lifeline, WB?
