Religulous is blatant about Mahers feelings: religion is bad. All religions are bad.
Actually there is one religion that he advocates. Atheism. Utterly supremacist in his view that all other religions (other than his own) are bad.
There is another incoherence. If religion is just another product of some impersonal stochastic, physical process of evolution, like gills on a fish, or Bill Maher, or any other concatenation of atoms, how can it be said to be "bad"? How can evolution produce something "bad"?
Cordially,
Atheism is lack of belief and therefore not a religion.
