As for getting even with Leftists, I could care less which god they worship. I'll let my G-d sort it out...
Believe me, I know where you're coming from! I was a pro-Israel Fundamentalist who joined the John Birch Society in 1977 because I thought they shared my beliefs. I can't tell you what a shock it was to discover that so many "conservatives" were hostile to Israel.
The quasi-official theology of the JBS is "chr*stian reconstructionism," an anti-Israel ideology that is very, very different from the Pre-Millennial Fundamentalism I grew up with. Many JBS coordinators (at least in the past) peddled an anti-Israel book entitled The Rapture Cult "on the side." According to this book, both the State of Israel and pre-millennial Fundamentalism are plots of "the conspiracy." I believe the full text of this book is available online. This anti-Israel position is also elucidated on a viciously anti-Jewish site called "We Hold These Truths," which is run by a man named Chuck Carlson (not to be confused with Chuck Colson!). It features a nasty little department labeled "Pharisee Watch."
For a long time (and I didn't know anything about this growing up!) even mainstream conservative publications like Human Events and National Review were pro-Arab and anti-Israel. And during his first term in the Senate Jesse Helms, the Southern Baptist per excellence, was also rabidly anti-Israel and even called for the US to break off relations with Israel at one point. Thank G-d he changed and was staunchly pro-Israel for the remainder of his career in the Senate.
When I first joined FR in '99 it was infested with Jew-haters, some of whom used the names of notorious Nazis as their screen names. Most of them (but not all) have long since departed. I hope you understand that was once exactly as you are and didn't have the slightest idea that any "conservative" was anti-Israel. I learned the hard way. For a while there it seemed as if pro-Israel conservatives had no political representation at all, since almost all the conservative politicians were anti-Israel. I believe the Internet has empowered the old-fashioned Bible-believing pro-Israel conservatives to contest with the anti-Semites and has played a role in making the conservative movement pro-Israel. Thank G-d!
At any rate, I've been around the block. I know where you're coming from (it's where I came from as well), but believe me (and I say this with no joy whatsoever) that for a long time "conservatism" was actually quite hostile to Israel and some of it still is. I know what I'm talking about. I've been there. And I learned the hard way.
