I notice that my question was never answered. Obviously nobody here is going to be against Zionist Christians, but do you feel that we are fake Christians or heretical Christians?
I believe that many of the scriptures can and are used in a whole lot of different ways. Different people can and do justify their ways using the scriptures especially the gospels and the koran. I also generally feel that people (mainly preachers of all faiths) for the most part have an idea or feeling and then use scriptures to back them up. You can come with strong support for Israel using much of scripture and the many warnings and admonition to the nations that G-D gives in the Torah (what you call the "old testement" and which is part of your belief) and perhaps from the "new testement" (which I know little about) as well) while at the same time I also believe that the haters of Israel can do things similar as well and history as well shows that to be the case especially with the church.
I can also understand (Askeansi) Jews mainly being frustrated for what their families went through throughout this long exile especially in Europe.
That being said people's beliefs are their beliefs. No one is out to "convert" Christians out of their faith and their is understanding at least from the Jewish point of view that people have deep rooted beliefs. Different sages even said that Chritianity and Islam are not idolatry for non-Jews practicing them (for Jews different discussion), not that Jews should encourage them but we can accept different beliefs. Also even pointed out that these beliefs bring the world closer to recognizing the truth (to be objective I'll state) according to Jewish belief (Torah and tradition).
Also perhaps their is misunderstanding and confusion of labelling people. Christian or not bacially the Jewish response is- whoever you are, whatever you would like to call yourself- don't mess with the Jewish people, Jewish G-D and society. If you are cool with us, were cool with you, if you try to harm Jews in any way- physical, psychological or spiritually then we have a problem.
