Agreed. It's not right to single out any religion, particularly insomuch as some flavor of this insularity can be found in every stream of religious thought that has ever existed

Generally, I have low tolerance for any group that segregates most of their existence from the greater whole - but then demands accommodation from the greater whole. Most Jews, Christians and Muslims do not - but some do - those communities who refuse to participate in broader society are in my mind inherently forfeiting their place at the table - simply put, you cannot expect broader society to accommodate your particular needs if you don't participate in it.
