They're right.

"You can't clearly define what makes an assault weapon different from a regular gun" Okay, fine, let's ban all guns to be on the safe side

"It happened in a gun free zone! A good guy could have stopped it!" The murderer shot THROUGH THE WINDOWS FROM OUTSIDE doofus

"Most murders are with handguns, not with rifles!" Ok, agree, let's get rid of handguns too

"But I won't be able to hunt" Ok fine, we'll allow bolt- and level-action rifles that people mostly use for hunting anyway. You don't need an AR for hunting deer.
