My opinion is similar to yours but as I get older I realize my opinion doesn't matter to anyone else except maybe a family member who wants something. I could never understand why someone who has dozens of firearms even has a waiting period. Does each one make you a little more dangerous?
I think it's impossible anymore to separate the laws that someone wrote in a good faith from those designed just to make gun ownership more painful for us. I just oppose them all on principle.
Waiting periods were originally sold as a way for someone who got angry and went out to buy a gun to shoot someone right now a chance to cool down. Intellectually dubious, but if true, they should never have applied after the first gun, because no one who owns a gun needs to run out to buy one if they wanted to shoot someone. So was it a misguided, but good faith, attempt to help, or a lie meant only to burden us from the start? Does it even matter?
