Large parts of South East Asia are either Muslim or part Muslim (eg India, Bangladesh, Sri Lanka, Malaysia, Indonesia (mostly peaceful WRT religion), etc. Some have had (or still have) separatist problems, but by and large they're ok.

There are also parts of Africa and Europe where there aren't problems.

I think the problem is cultural - Islam's teaching may not be helping, I'll agree to that - but look at Northern Ireland. Ostensibly that was (is) a religious conflict but it isn't.
