Among my friends also have a lot musuliman. We have never had a conflict on this basis. They are balanced people who respect the tradition of others.
I have a lot of Muslim friends as well. Never had a quarrel with any of them. But then, almost all of them want the Shariah law to be imposed (even for Non-Muslims), and want non-halal food banned. I can never support such people.
If they are in Foreign lands (Non-Muslim countries), then, they have no right to ask for such thing. They must impose Shari'a on themselves, not others. On the other hand, If they are in a Muslim country (where Muslims are the majortiy), they have to impose Shari'a on Muslims and Non-Muslims and to ban the non-halal food (like Pork, Wine and Alcoholic drinks). That's what Islam told Muslims to do.
