Of course you are omitting the Messianic Jews on purpose, right? They are Jewish by genetics and Christian by their chosen faith. I know several and they would strenously object to being told they are not Jewish Christians. :o)
I am not. Messianic Jews are Pharisees/modern Jews who believe in the coming of the Messiah (who hasn't come yet) and the resurrection of the dead.
If you are referring to a Christian sect that calls itself "Messianic Jews," you bet I am leaving them out on purpose.

I am sure they would. However, one thing all Jewish sects agree on is that one cannot be a Christian and remain a Jew, just as one could not become a Muslim and remain a Jew.
