Someone should knock some reality into these punks.
Why?
Are they hurting anyone?
Is it costing you money?
It is a fad. Nothing I would enjoy doing but obviously others do. It is no different then what goes on at the Comic Book conventions. Dress up and pretend.
I would also say it is no different then a bunch of guys “dressing up” to go fishing for a day or even hunting.
Hint: they call themselves punks. Maybe they should join the reality-based community.
