Secular gov'ts are the only gov'ts capable of not interfering in personal religious practice as they deal only with practical day to day affairs, outside of the religious sphere.
incorrect.
based upon the painful but obvious truth that in many secular governments today many people's religious freedom is quite interfered with.
in turkey and france people cannot wear any religious clothing in publi (ie government) buildings (france being specifically schools. the ban in turkey may even be limited to muslim articles). jews cannot wear a star, nor christians their cross, and muslim women cannot wear their headcovering. why? the government is uncomfortable with it. but it is more than a matter of comfort with the adherents.
to be fair, the french law is attempting to limit disruptions in classes, but that's about as useful as dress codes over here. you cannot treat the symptom and expect a solution.
