No seriously, you practically can't be a Christian unless you know and understand that God's chosen people are the Jews.
If a supposed "Christian" hates Jews they're literally going against God therefor not making them Christians.
Hmm, there are two definitions of Christians that I have heard. One is those that believe that Jesus is the son of God. And others that simply follow Jesus's teachings and may or may not believe that he is the son of God. (There are actually athiest Christians. Crazy no? They do not believe in the divinity of Jesus or even in God, but they do see him as a role model much as someone would see Ghandi as one)
