You seem to be under the ignorant impression that you have to fire a certain number of shots before ear damage occurs. Ear damage occurs with sounds above 85 dB. An unsuppressed AR-15 is 165-175 dB. Even a single shot can result in permanent ear damage and tinnitus. If you are close enough, it can deafen you. A suppressor can reduce that to around 130 dB. Still enough to damage your ears, but perhaps enough to save you from hearing loss.

Also, I didn’t say I was worried about their ears. That’s another thing you’re mistaken about. More than just nazis have guns. Many leftists do as well. I myself have a AR-15 chambered in .300 Blackout, as well as an AR-15 in 5.56, among other weapons.
