Cars and guns can't be compared it's not logical! There are a lot of things out there that kill people. But if you want to compare a gun, compare it with something designed as a weapon. I mean come on, cars aren't really used or designed for attacks! Cars kill more people yes, but you don't buy one to keep it in your garage for when an intruder comes in, so you can quickly fire her up and run someone over. I know the argument is that more deaths are caused by cars, but not usually intentionally. I'm sorry but I find this comparison illogical.
I live in a country that forces me to be defenceless? No. We have knives, baseball bats, pepper spray, axes etc. We don't however live in fear of someone coming in and threatening us with a gun, it rarely happens, so we don't need guns to counteract. The home invasions people I know who have experienced them here a gun was never involved. If I want to arm myself, I'll arm myself. I don't need a gun to do it. Not in my country. And I'm happy with that.
Ok lets talk logic.
Again I have seen many people intentionally run over by cars. A pissed off spouse or acquaintance. It happens all the time.
If you really want to about this on a logical level then you have to accept the outcomes as a logical conclusion as they are factual. If person A gets in his car and drives over person B because he saw her coming out of another mans house; his intent was to use it as a weapon. It doesn't matter how you see its original design. It is what it is.
More logic for you to ponder. Who follows gun laws? A. law abiding citizens. If only law abiding citizens follow gun laws the net affect would be that only criminals have guns. The logical end result would be that the law abiding citizen is defenseless against the criminal element. I have faced down the barrel of a gun more than once and I fully understand the most basic concept of human nature is self preservation.
If you want to defend yourself with a knife or a bat; ok by me. Logic would dictate, never bring a knife to a gun fight. You seem to key in on home invasions. this is a very small percentage of crimes Which is the point in ccw permitting. I take responsibility for my on safety. I will not wait for police to show up and save the day. Generally they show up after the crime is committed and a victim has been created. I don't intend to be a victim.
An earlier post of yours stated that your stance is an idealistic one. Ideology and logic quite often are mutually exclusive. Reality and outcomes trump idealistic intent.
Finally,If you really want to pursue this on a logical level you might read a book "More guns Less Crime" by Dr. John Lott. it is the most extensive study of gun laws and the result ever done. If as you stated earlier you are more ideologically driven you will not like it.
