Gotta agree with you there.
From what I've seen they've only ever bashed two religions: Mormonism and Scientology.
They've done plenty of hypocrite bashing in both Christian AND Muslim circles. And even there Muslims/Islam are treated much more harshly than Christians/Christianity.
They weren’t even all that hard on Mormonism (except for the whole “stretching credibility, even for a religion” thing). They were very complimentary of the culture of family stability that Mormonism has created for its practitioners
