However since some jews have converted to christianity, christians cannot claim that jews are inherently evil from a genetical standpoint, for it would bring incoherences within our faith.
So no, I disagree with you, xyr.
Also even within jews who don't convert, there's a lot of them who don't even believe in God nor in their traditions, making them no different than atheists in my mind.
And if I have no problem voting for an atheist (which I have but it's the best I got), then I shouldn't have a problem voting for an ethnic jew who in regards to his beliefs is no different than an atheist.
