Far too many people either do not know what the 2nd amendment is or do not understand it. You are 100% correct in stating that many people only care how something affects them personally. I would venture to say that a surprising amount of hunters(even long term hunters) favor the magazine and/or "looks evil" rifle ban.
We are a minority group(2nd amendment advocates) within a minority group(gun owners) and have one heck of a battle coming up. We need to go on offense and fight the fight like other minority groups in America fought to get what they were seeking.
