Why would that question make you furious? Isn't discussion good? What a great opportunity for kids with anti gun parents to hear a different perspective.
How can your typical modern middle school student present a considered argument for OR against the 2nd Amendment? They probably haven't been taught much (if any) U.S. history at that point in their educational lives.
Gun control has always been taught in school. I distinctly remember having to write several papers regarding gun control in high school - in the early 70's. I was the ONLY student in my classes to argue *against* gun control. Teachers, by their very nature are generally liberals in their thought processes, so it really shouldn't surprise anyone here that this assignment raised its ugly head - even in gun-"friendly" Texas.
