How does me checking the person I’m selling to, stop me from my right to own a gun, or how does me checking someone stop their right to legally own a gun? The second amendment says nothing about selling. I own a few guns, and I have no issue doing these things to sell my guns, to make sure the person I sell to has the right to purchase it.
Some people don’t have the right to own a gun, and it’s our job as citizens to do what we can to keep guns out of hands of people who shouldn’t own them, wouldn’t you agree? Instead of waiting for them to shoot up a school, and then someone being hailed a hero because they legally owned a gun, and stopped him/her. This is like being the hero that doesn’t wear a cape.
