That might be a bit harsh, Sam, but yeah, on the principle of it, it had certainly crossed my mind, and me and thee can't be the only ones. But I don't think invoking Hitler in an EU debate is a terribly constructive way to conduct what is, after all an extremely serious referendum question, the implications of which are very large indeed.
EDIT - Oh, and I mean the national debate, not this thread. It's not a pop at you, Sam.
