I don’t really care about having a protected class. What is important is that giving “God” and kind of standing outside of private homes and churches is rubbish. Stop doing that and atheists , agnostics, nature based religions, pantheists , polytheists, won’t have a valid reason to feel oppressed or even insulted . As It is, God based religions , in this country primarily Christians or those who pretend to be Christians are given the upper hand socially and culturally and that leads to having advantages in other areas. It’s affirmative action promotion for believers.
