A gaping hole in much of Christian theology is that Jesus discards Jews and others like trash and burns them alive forever. That isn't at all how it works. Jesus will unite ALL THINGS in himself. The following scriptures describe that God will have mercy on ALL.
There are bad Jews but they nonetheless remain God's chosen people and we should support the will of our Father by supporting Israel.
Romans 11:29-32
For the gifts and the calling of God are irrevocable. 30 For just as you were at one time disobedient to God but now have received mercy because of their disobedience, 31 so they too have now been disobedient in order that by the mercy shown to you they also may now[e] receive mercy. 32 For God has consigned all to disobedience, that he may have mercy on all.
Your problem is your inability to distinguish between Jews by race and Jews by religion.

Was John referring to Jews by race, or to Jews by religion?
1 John 2:18
Little children, it is the last time: and as ye have heard that
antichrist shall come, even now are there many
antichrists; whereby we know that it is the last time.
1 John 2:22
Who is a liar but he that denieth that Jesus is the Christ? He is
antichrist, that denieth the Father and the Son.
