That's a good point, so let's start with first principles:
- I don't care what belief you have or how you manifest that belief when it comes to your individual choices of what private goods to consume, e.g., pork, beef, holy water, trips to some sacred place, etc.
- I don't care what belief you have as long as you pay "your fair share" towards public and club goods such as roads, environment, etc. That means pay your taxes and no deductions for religions (or charitable contributions, etc.)
- I DO care when you vote or act to deplete community (common pool) goods because your religion says that adverse impacts towards infidels or future generations is either irrelevant or condoned.
The same can be said, btw, for people who behave as homo economicus (me first, screw you) or who have lobbyists to steal from the majority to give to the minority. Those people are just as anti-social.
Did I miss anything? (I included BOTH politics and religion :)
Bottom Line: I don't care what you believe; I care what you do. "My god says so" is no excuse for anti-social behavior.
