I heard that these fellas are a small group of young radicals. They haven't killed anyone yet. Just been disruptive with spitting on tourists and screaming at them and such.

As a Christian I would prefer to be in Israel than any Muslim nation. Pogroms against Christians is not state policy. Apparently mission work is banned in Israel which is weird. They are dependent on Christian tourism so hopefully there is a limit to how bad things can get there for Christians.
