A person's values and opinions are not inextricably tied to their religiosity. I'm about as irreligious as is possible to be, but two of the nicest most intelligent and genuinely nice guys I know on the planet are respectively a devout Mormon and a guy who's a serious evangelical Christian who does ethnic Chinese American rap and last I checked is planning to attend seminary.

Point being, say no to monoculture, say yes to having interesting caring people who enrich those around them.
