The rest of your post is clearly an idealogical view on the right to use firearms for self defence. The people who want semi-automatic guns banned but allow people to keep conventional hunting rifles obviously don't agree with you (on either that you should be allowed or if you are, that those types of weapon are necessary for it). I don't especially want to get into that here as it's not the place, you aren't going to convince me that I need a gun to protect myself (or that if the government or police wanted to get me having a firearm would help) and I doubt I could convince you otherwise.
