What is your justification for regulating this right differently (apart from you being afraid of firearms)?
Didn't we have this discussion already? Why on earth would I be afraid of firearms? That's just a sad attempt to de-legitimize opinions you don't like. To turn it around, why do you want such unrestricted access to guns? Is it because you cower in fear from others all the time?
See how silly that is?
Again, why not background checks for automotive purchases? Or any other dangerous object that could be used somehow to create mass terror / casualties?
Because guns and cars aren't the same thing as cars are a far more integral part of our society. As with all regulations there is a balance to be struck, and the idea that the balance for a car and the balance for a gun would be the same is nonsensical.
