Care to rephrase that? You seem to be asking why Christians support Israel, which is quite a different thing, then supporting Jews.
I support my local temple because they are a nice bunch and their rabbi has been very patient with all my questions on the Law.
I support Israel because I always support the civilized over the barbarians. I support the law abiding over the law breaking. I support those who build over those who destroy. I support freedom over slavery.
So, I support Israel.
Thank you for improving my question...
