Earlier quoted context omitted.
Somehow I never read news about "rapist shot dead by attacked woman". Are you positive that buying more firearms will make it happen? Because it definitely doesn't look we're there yet.
In most incidents where people use firearms to protect themselves no shots are fired, just brandishing the weapon is enough. Those incidents don't make the news. Buy if you're looking for an actual news story, here's one. https://www.wtol.com/article/news/local/resident-shoots-woul...
The comment is probably not meant this way, but brandishing has connotations of anger, excitement, or intimidation.
I would caution one not to do this as it may be illegal in your jurisdiction. Only draw a firearm with the intent to use it, not with the intent to intimidate. Certainly, the intent to use it may have a side effect of intimidating an aggressor — I don’t dispute that.
