This is the reason for the profundity I found in the interview with Ruslav Tsarni, the Tsarnaev brothers' Muslim uncle who, convincingly, I believe, denounced armed jihad and expressed a genuine devotion to American values. Americans are free to view Tsarni's testimony as taqiyya (a religiously sanctified lie to advance Islam, as many commenters on the article apparently believe), but the point is, the message that there are Muslims who abhor Islamic violence and value freedom is much better-received by such an example than being told what to believe by a leftist opinion-maker.
Likewise, hearing a leftist opponent of religion denounce the notion of religious parity while speaking the truth about Islam's role as a uniquely malignant contributor to global terrorism is much better-received by leftists when heard from Bill Maher than from Pamela Geller, who, in my opinion, has been wrongfully ostracized from the discussion among leftists.
So, thanks to Bill Maher, the anti-jihadists' message may have found a new audience. And truth, when allowed to permeate any dialogue, is never a bad thing.
