Rae,
I questions your assertion that slowly but surely our religious freedoms are being eroded. Looking back at the history of our country, I think we're living in a pretty enlightened time. No witch trials, no being turned down for a job, house, etc. based on religious persuassion.
Yes, there are some people who react badly to beliefs they aren't familiar with , or don't themselves follow, but religious persecution is not blatant (and fatal!) the way it was in earlier periods of this country's history.
What really helps is the average educational level of the general populace. When you know your rights, it's harder for people to take them away!
