What about expecting your surroundings to accommodate your religion? At what point exactly is that going too far?

Sure, in the same way that not knowing how to count or add and subtract numbers doesn't technically hurt anyone. But it sure as fuck stifles their potential in life and they would definitely be better off getting educated on the topic.
