If you know so much about firearms, explain bump stocks.
I don't know all that much about firearms, I've just been doing this exact same argument for the last 20 years. I think bump stocks are stupid. But since they've only been used in one crime ever (I've never looked that up, but I've said enough times and nobody has ever questioned it, feel free to prove me wrong), I think it's dumb to ban them. But since they're dumb, I'm not going to argue against banning them (ya know, compromising. The thing both sides have to do sometimes.).
it would be best to target something that might actually do something.
What do you suggest will work?
punishing people harder that use guns in a bad way. Punishing people that are not supposed to have guns but get caught with guns much harder. Punishing grandma more when she buys a gun for Tommy because Tommy can't buy a gun because Tommy has a habit of knocking over 7/11s (straw purchases).
