A gun makes a great defensive weapon because it has the potential to be used offensively. The Left has known this for decades; hence everything they don’t like being tagged as “offensive”. A purely defensive weapon would be a heavy desk to cower under and an acceptable offensive weapon is a stapler to throw at the perp as a last symbol of defiance as he shoots holes through you.

Law enforcement aside, there are aggressors, many with guns. When they assault you in your home, a defensive weapon can be used to repel the assault and kill the assaulter.
The aggression weapon during the assault is an assault weapon regardless of caliber or configuration.
Anything which can be used as an offensive weapon can also be used as a defensive weapon, the difference is merely a matter of who initiates the violence and who is attempting to defend against the violence. Any man who would seriously contend that a gun only falls in one category, whether it be defensive or offensive should not be trusted to do anything more complicated than cleaning toilets.
Someone should ask this clown what the person who shoots an intruder who breaks into his home is doing. If he is not “defending” his home with a gun then what in hell IS he doing?
