I'm Roman Catholic. Our close circle of friends from school is very diverse - Jewish, Muslim, Atheist. The past 5 years the Catholics from different national heritage seem to have increasingly more in common. From how we handle friendships, relationships, family, work and traditions/authority in general.
Even though I'm an European Nationalist, you'll be hard pressed to find me attacking Islam. Because I admire certain aspects. One doesn't need to attack opposition to prosper, just celebrate & showcase why your way is worthy.
