I just think it's unfortunate that people have been sold a bill of goods about bike helmets that is incorrect. and when you point out that it may be incorrect in certain ways, some people get really defensive about it, almost like it's a personal insult. and then..... the insults start flying, with words like stupid, Darwin, organ donor and gene Pool being prominent favorites.
