Why would you be against someone protecting their irreparable hearing? Do you even know how much a suppressor reduces noise to begin with?
If you could point out precisely where I'd said that I'm against someone protecting their hearing, I would appreciate it.
The instant jump from "He's asking why anyone would actually need a silencer in practical circumstances" to "He's against making silencers legal" tends to speak volumes. Guessing all that gun noise somehow affected your reading comprehension, too.
