All that is very true, and it would be a great justification for more gun control if gun control was actually effective. But because it isn't, and because police are often useless when you actually need them, you're often going to need to be your own first responder. My sister and I dealt with a home invasion from a disgruntled ex-boyfriend (hers), who legally wasn't supposed to be able to possess firearms (and yet he did), and the police were next to useless. Baltimore City police are incompetent dipshits.
But the bigger issue I've found is that because guns are scary (I'm not being sarcastic, I understand being nervous around firearms), going full Ben Shapiro and jabbering at women with facts and figures never works. It's awkward and everyone gets quiet and uptight and doesn't erase their actual feelings.
Likewise I've found it super difficult to peak women on troonery because for a long time, I approached it like I was talking to another man. With facts and figures. Doesn't work that way.
