1. Never ever compare things to World War II, the Nazis, Chamberlain, or anything even remotely connected to Hitler. Like Jon Stewart says, you know who was as bad as Hitler? Hitler.
2. When you say something that gets you into hot water, don’t try and bring it back up six months later. That’s why you don’t see Scott Reid going around saying "you know, I was technically right on the beer and popcorn thing". And that’s why you don’t see (or hear) Tory backbenchers.
3. If something has been compared to "the political equivalent of a kamikaze mission" (again with the WW2 references...) and you were skewered for saying it the first time...you might not want to call your original remarks an "understatement". Again, I hate to use Scott Reid as the role model, but he hasn't said anything like "you know, beer and popcorn was an understatement; single moms could spend the cash on crack and NDP memberships".
