You don't need to, the self defence bullshit is a fallacy. The reason why folk scream about guns is that people are getting shot (that's the ******* gun debate), and here's you saying you have the gun to shoot the one in trillion enemy/rapist/murderer.
And it's not banning guns, and it's not your current system or handing them out to every Tom Dick and Harry. It's having common sense with guns, stop giving them to the unsuitables. The world has been screaming this at you bumbshits for decades.
One example of common sense. When someone applies for a gun, scrutinize their social media. The Lefty women on TikTok that posted videos they want to shot men, straight away they're unsuitable to own a gun. Then retards like you will come mouth frothing in, "Barf barf, Rights, mouth froth, Rights". And then you're totally perplexed on why folk shoot folk.
You are thicker than my kitchen worktop.
