where is the anecdotal or other evidence that Jimmy couldn't say his blessing?

If there was such a case, shame, stupid. But I don't believe there has been or ever will be such a case.

Make up something more egregiously outrageous and stupid, and people will again say, 'yeah that's wrong'. But it hasn't happened.

'Jimmy, say all the prayers you want at lunch or anywhere else'. Some other kids might make fun of you if your lips move too much, but kids are cruel.

There are courses in History of Religion in must colleges and universities, some high schools, but my fear is that courses like this might become teach all about Christianity for 8 months and spend a month on all the other religions, if that. And again, I have no evidence, anecdotal or otherwise, that this has ever happened, and so I'm not giving an example of what abuse has occurred, but I can see that it might happen in some communities. And ad hominem attacks do not advance your argument or support your theories. to each his own.
