Donald, I now understand what you're getting at, though I don't actually like the example of seat-belt laws, which are not really peaceful. There may be a justification for such laws, perhaps a paternalistic one, and I don't want to argue against them. But the fact remains that the state will fine me - or in the ultimate, should I refuse to pay the fine, confiscate my assets or send me to prison - if I don't wear a seat-belt. Thus the legislation is backed up by threats of violent acts by the state's servants.

However, I realise you don't say that anything like that should be done with religion. It's just that a successful campaign of ideas could place religionists in a position where they will have little practical choice but to abandon their aspirations of wielding political power. On that, I fully agree. If that's all you mean by "force" them, then we're at one. That's just the situation that we need to try to bring about.
