Do we need to know about firing pins and shit like that to know they make holes in people when pointed at them and discharged? I don't give a shit what you call them. Besides it's not simply about the hardware. It's about adequate background checks for legal and mental health issues, regular licensing to validate the user is proficient in the safe use of their weapon, tracking where the weapons are to verify they are in legal ownership, legal standards for safe storage in a manner that prevents a child from being able to fire it if they get their hands on it and of course, some kinds of guns should be banned or heavily restricted. I don't know why you gun owners haven't asked for these measures and worked with lawmakers to make sure it happens. But, your time is up. The tide has turned and non-gun owners along with the many gun owners who do support more restrictive gun owner laws will just do it without you. You can go back to sleep now.
Once systematic gun control measures are in place, it won't be so bad. As long as you follow the law, you can keep your guns. You might even thank us for doing the work you should have done.
