Very much agree. I'm not a great supporter of thinsulate anything. Layering for extended outdoor activity has always been the rule. What you wear is determined by what you have - that's the reality of the situation. If you are actually winter camping then selection will be crucial. If you are outside for short periods of time and have access to excellent shelter you don't have to dress like the arctic man. I mentioned the buddy system in another thread - we use the buddy system when involved in winter activity to watch for frostbite.
