Religion is arrogant when they use that as an excuse to decimate the population of indigenous people, when to force people to give 10% of their earnings to an institution, when they try to infiltrate their belief into a secular system, when they judge you for not having their same belief system... and, as a personal anecdote, when even the teachers bully you in your religious school because you chose not to go to church with the classroom.

Believing in something with no evidence or statistical confidence is arrogant because your belief says that everyone else's belief is wrong.

A more humble approach would be to just accept your ignorance. Specially when you try to push your belief into reality, like politics, like most religious people do.
