You own them out of the childish sentiment that having them pisses people off. Do you really not get how immature that is?
And your solution is to go out of your way to antagonize people by owning weapons you never intend to shoot? Way to contribute, dude.The perception of the antis is irrelevant. It's been tried and they will just continually take and take. Appealing to them is a waste of time when you can make their opinions irrelevant.
