My perception, from deep in the heart of Texas, is that all Christians support Israel. I know that's not the case everywhere, but it is in Texas. So, the backlash about the Passion, from some, was confusing for me. Genuine Christians will support Israel and love the Jewish people because they believe in G-d, not for anything lovely about us. The others will turn on us. It is inevitable.
What you say is true..People will support what G-d wants, it's not about people but it is about G-d....
