Clearly not. The Jews who advocate mass immigration turn on a dime to protect Israel. They believe none of what they say. The non-Jews in the left aren't any more faithful - they're craven rather than self-interested. "Lefties as true believers" is a terrible predictive model, and anyone who internalizes it becomes less effective.
