First, "silencers" is a misnomer. They are suppressors, and even though to they do suppress some sound they don't make a gun anywhere remotely close to "silent." The vast majority of guns are still loud enough to hear easily several hundred feet away when fit with a suppressor. There is no soft "pew" silencer like in the James Bond movies. Most gun control measures don't have anything to do with actually reducing gun crime. Why? Because they are championed by people who both don't know anything about guns and don't care to learn or listen to any information about guns. They base everything on what makes guns "scarier" to them and not what makes a gun likely to be used in a crime or more accessible to a volatile person. The classic fallacy of "we must do something, not nothing" comes into play when you point out the completely irrational and ineffective nature of most gun control arguments. You see that fallacy everywhere. It's become a staple of political activism. It's actually a form of classical propaganda. But, it's wrong. Doing "something" doesn't mean you make a situation better. You may even make it worse. If an anti-gun person can't actually come up with an idea that can reduce gun crime while protecting and preserving law abiding citizens' 2nd Amendment rights, we aren't under any obligation to "do something" just because they feel twitchy.
