When I was in elementary and jr high school we recited the Pledge. But if a student or parent had any objection to reciting it all it took was a note from their parents and they were excused, no questions asked. And our parents and teachers admonished us in no uncertain terms not to harass those kids and respect their views, just as they were expected to respect others as well. But once again we see anything that was sensible then is inherently eeevil and rayyycist.
When I went to grade school in New York, the Pledge, and basic public schooling, were seen as things which united a diverse group of Italian, Irish, Southern Black, Jewish, Puerto Rican, Lebanese and Greek students into at least one common identity separate from their diverse personal identities.
No one was exempt - and no parent would want their child to be exempt.

I'm sure it would have involved my parents, the Principal and a sizable piece of wood.
