Doesn't matter if they are isolationist or pacifist...neither group is living in reality.
And you can't stick your head in a hole and pretend they don't exist, as the isolationists here do, nor can you reach out your hands to them and sing Kumbaya as the pacifists (some here as well) do.
Real life requires real answers. Sometimes they're not easy, but neither running away nor chanting about 'peace' has never solved a single problem in the real world.
