I see no reason why one should consider it being hostile to Jews to preach the gospel of Jesus Christ to them.
Preach the gospel to them, try to convince them that Jesus is not only their messiah but the messiah of the world.
It is up to them to accept or reject the message. Nobody should be coerced into believing ( because to do so would be meaningless ).
Above all, continue to show them love and respect even if they disagree with you.l
AND LEAVE THE RESULTS TO GOD.
