Not true. Sentencing under Due Process can have lifetime consequences beyond prison time, including permanent loss of some rights. That’s not to say it makes sense (which your comment does,) but it is Constitutional.
There is nothing weird or arbitrary about it. The distinction between ordnance and arms has been around for many centuries. As usual, your opinion sucks. (“Fighting words” … )
Both the First and Second Amendments are absolute (“make no law abridging” and “shall not infringe” are precisely clear.) What neither the 1st or 2nd Amendment do is absolve you of responsibility if you do harm with your speech or arm.
Why are you confused? The Bill of Rights are restrictions on Government power. By saying nothing about explosives, they allow the government to regulate them as much as they want to.
Your confusion is total. Nothing about the 2nd was a compromise to gain support from any State. The compromise to appease the South was about counting slaves as 2/3 of a person for purposes of representation rather than not counting them at all because they weren’t actually going to be represented at all.
Did I say that he just snapped? His poor mother was trying desperately to connect with him, Her enjoyment of shooting sports was something she tried to share with him. But she still kept her guns lacked up and still you want to blame her for letting him kill those kids.
It doesn’t matter what he insisted. You insisted that “more than half” of the States had safe gun storage laws. That is wrong … just as @Oldandtired said.
