If we put background checks on gun buyers, hardly anybody will get to buy guns, and we won't get those big fat checks

Not sure if you have ever purchased a firearm but there's a little form called a 4473. It's standard, has been for the better part of a century. You should look it up. And then I'm sure you'll present me with your argument about how more laws will make criminals stop being criminals or something...

I think what he's trying to say is that less unfit shoppers will be able to purchase guns, and thus, the gun companies won't get their money.

Problem?

And that relates to gun companies losing money, how?

Because what you are asking for is already required. Yet people still buy guns.

Well the unfit shoppers don't get to.

They get the guns illegally instead, just as they do now under the rules that you want that are already in place.

What does that even mean?

It's when you fight something that isn't actually real

Well when they obtain the guns illegally, the gun companies don't get paid.

So basically you're fighting shadows.
