How are the Jews God's chosen people if they don't accept Jesus Christ as their Messiah?
It is basic Christianity! Whoever becomes Christian and accept Jesus Christ can take part of the New Covenant made with the Church who is the New and Real Israel.
Jews are not God's chosen people! They crucified Jesus Christ, they reject Him, they don't care about Jesus Christ at all. These people are just religious people. That's what they are. Whoever accepts Jesus Christ as the Messiah is part of God's Israel, of God's chosen people.
Don't believe for one second that you will intimidate me and my strong beliefs that Jesus Christ is the Messiah and that His Church is His true Israel, His chosen people. You want to call me an antisemitic? So, call me one! Saint Stephen also was one when he was angry at the Jews for their blindness and obstinate rejection of Jesus Christ. The Eastern Orthodox Church, too, scolds the Jews (in the expression of faith) for their stubbornness, for their hearts of stones, for rejecting Jesus Christ. They never put the Jews in Concentration Camps, never killed Jews, never preached killing of the Jews and. If you can't see the difference between scolding someone and killing someone than you have some problems! Also, the Churches who consider themselves the New Israel are the only ones that are truly aware of their Jewish roots. The Churches who fail to see the organic relation that exists between the Old Testament and Covenant and the New Testament and Covenant are blind people who don't even understand what they believe in, why they believe what they believe and so on.
If you want to say that God didn't fulfill His promises towards the Jews, very well! But don't call yourself a christian when you choose to say so! Have some decency, you and people like you!
Here's a video that shows how Israelis see Jesus Christ:
