Personally I couldn't care less what religion he was born as - he's a bastard now and that's all that matters. And who's to say his mother didn't convert before marriage?
I couldn't care less either, but I just wanted to know for myself why he is such strong supporter of Zionism, not to say there are no christian zionists of course.
I read somewhere a while back that a lot of European Christians converted to Judaism in the 16th-17th centuries in order to avoid taxes that were demanded by the church - maybe that has some bearing in this case.
And I heard from a Jewish friend of mine that around the same period you mention,
a lot of Georgians had to convert to judaism cause the king married a jew and forced the population to convert.
He also says that a lot of us don't accept these Georgians and we kind of ostracise
them.
