Yes, for to be a Christian is to be a Zionist.
Would that the Zionists believed that in its reverse, or, at least, in a “Christians aren’t bad guys” sort of sense. The Jewish state does not allow immigration or visitation for Christian missionaries. To talk about Jesus on the streets is an invitation to be spat on and arrested. On the other hand, a Muslim immigration moratorium for Europe or the US would be radical, according to Netenyahu these days.
Wish you could convince many Left leaning Jews to be Zionsists as well...
