Define "common-sense gun regulations", because every time someone tries explaining what that means it is almost always the exact opposite of common sense. Is restricting suppressors common sense? Because some of the nations with the most restrictive gun laws advocate for the usage of suppressors. Or bans on the scary AR-15, which is less powerful than most 60 year rifles which nobody cares about, especially when the vast majority of gun crime is committed with handguns. How about bans on gun accessories like types of stocks, slings, or bayonet lugs? How about sawed off shotguns which are less powerful than many "pistols" that shoot rifle rounds? Or shotgun/rifle combinations which were once a popular hunting combination for small game.

Either we should be allowed whatever semi-auto gun, or we should be allowed zero. Everything in between is a complete waste of time and effort and just leads to fucking over poor people for judicial profit because they can't afford $10,000+ lawyer that gets everybody with any money off of such charges.

You don't cooperate with abolitionists using compromise. You will never come to an agreement that satisfies both parties. By definition it is impossible.

Interests are also not always clear, any movement that wants to restrict activities using the law, is going to attract opportunistic power-seeking individuals. There's always crazy carve out exceptions in these proposals that allow the wealthy and the powerful to use and possess firearms that regular people cannot reasonably expect to have. It's laws to protect the powerful from the everyone else. Billionaires are creating armed doomsday compounds in countries like New Zealand, while supporting legislation that makes it harder to own a gun for self defense.

Also mass shootings are statistically the least likely cause of a gun related death. They are in the news because they are novel, not because they are likely to happen to most people.

Calling anything about gun control laws "common sense" is disingenuous at best. I'm coming at this from the "you go left enough and you get your guns back" side of the whole debate, but it's extremely difficult to solve a problem that consists of "tool used for its intended purpose, but in the wrong context".

Guns kill things. That's their primary purpose, it's why they exist. The people who aren't interested in guns for that purpose are easy to please: they don't really care about gun laws except in so much as they stop them from buying fun toys. They'd probably be fine with wildly invasive processes (being put on lists, biometric safeties, whatever), so long as they were given something in return. Something like, "You can have machine guns, but they need to be kept locked up at a licensed gun range".

People who just want guns for hunting are likewise easy to please. I'm not aware of any gun laws that have seriously effected the people who just want to shoot deer, because the tool you use to shoot an animal that isn't even aware you're there is pretty fundamentally different than those you to shoot someone who doesn't want to be shot.

The problem is people who want guns because of their utility against people, whether that means self defense, community defense, or national defense, fundamentally need the same things ( a need that is very expressly protected by the second amendment) as the person who wants to shoot a bunch of innocents. The militia folk might be fine with restrictions on handguns, but handguns are bar none the best choice for the self defense folk. The self defense folk might be fine with the existing machine gun ban, or other restrictions on long guns, but the militia folk need those for their purposes. The self dense folk are probably fine with being put on a list, but the militia folk who are concerned about the holders of that list are rightfully opposed to that.

IMO, the most effective gun law that isn't a complete non-starter to any legitimate groups of gun owners is the waiting period. It's an effective policy that substantially reduces suicide. That's a good thing. Requiring sellers to not sell to people under 18, or those who are obviously a threat to themselves and others is also largely unobjectionable. Punishing parents who fail to secure their weapons from their children, also a good thing.

No one's in favor of mass shootings, but it's not anywhere as simple as saying "common sense gun regulations".
