Last night after my World War II GURPS game (sneaking a polish submarine past both British and German sub in 1940 is easy... when you are lucky), we had a little discussion about world politics. One of the conclusion we reached was that democratie might be dying because of one of it's strong point: tolerance of difference. Or more exactly the pushing back of the limits of tolerance, sure some limits of tolerance needs to be pushed back (because of society evolution and new understanding) some probably shouldn't.
One of the group we thought about abusing this limit pushing was religious extremist. Under the suggestion that we should respect their belief, they try to impose their belief upon us. They want to have the law of their religion replace or if it can't replace society's law they want their law to be superior to society's. Under the guise of religious tolerance we slowly must accept more and more law/politics that are against what we believe about. It's not something quick we slowly add a few right, a few permission that other do not have. Then the permission becomes an obligation for the other and pretty soon after what was once something we tolerated for a minority becomes something the majority has to has.
The problem, one of my friend exposed, is that you cannot discuss/negotiate with religious extremist, they are right. No argument from you or anyone else will convince them otherwise, at best they will say you are wrong and leave you be. At worse, well Jihad, crusade, inquisition, war or slavery. It's rare but I'm gonna take a page from France on what we might want to do: our society should be completely irreligious. Everything that is public, i.e provided by the society, should not accept any religions symbols or propaganda. No veil, no cross, no knife, no angel, no star of David, at least in public institution, if you want to create a private school where you can (or have to) wear such symbol, good but you have to prove that you do teach everything a school should teach and that you are not discriminating against people.
