Exactly. Each and every sect thinks it knows better than the other sect, and knows better than anyone else. It doesn't matter if the ideas conflict with science. Faith means not listening to anyone else's argument with an open ear. Quite the contrary.
Men and women of faith are praised and held in the highest esteem for being steadfast in closing their minds to ideas that might contaminate the dogma.
I find that most visceral attacks against religion are not made in a response to actual incidents of religious people engaging in a "I know better than thou" attitude, but rather, by the conscience of those who reject religion and God.
Furthermore, those who attack all religious people, and faiths with a broad-brush are exhibiting the same disrespect, dismissiveness, ignorance, and outright arrogance that they claim to be rallying against.
