We all agree felons shouldn't own guns.
No, we don't all agree to that. A large number of us agree that if someone is free to walk the streets with the rest of us, he's free to keep and bear arms, regardless of his background. Period.
No we do not all agree that felons should not have guns, some of us believe some people should not be labeled felons for many many crimes.
This. Bears. Repeating.
