Excerpt from a recent interview with Moshe Feiglin:
You talk a lot about getting funding from outside sources. I read that you wanted to stop accepting funding from Christian organizations. You said, “but their goal is clear: to become citizens and convert us all, God forbid.”
… Behind money that comes from Christian organizations, there is always, by definition, a missionary agenda at a certain level. You can’t hide it. That’s what it is. And because we don’t want to be impacted by that, we’re not taking money from Christian organizations when we’re offered it, and we’re offered a lot of it. We do take from individuals. There is nothing about love or hate. It is about dealing with reality and understanding that reality.
