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.
