Give me a break. That was the worst dive since the World Cup. Most old ladies wouldn't go down after a push that weak anyway.
But yeah, if old ladies declare war on Libertarians, threaten you on social media, attack you and shoot at you, and if an old lady executes a couple Libertarians in cold blood (and threaten to do it again), and if an old lady comes up behind you and starts acting all crazy, and you (feeling threatened to begin with) push her away and she falls down, then yes...You are still responsible.
If all that happens (Grandma Hillary is a possibility in two years, and she is no friend of Libertarians, just saying) I will be the first person to defend you.
Promise.
We also don't know what the moron said to the cops, not that it matters, but if it was along the lines of impregnating someone's wife, then the moron got off cheap. We might be better off, as a society, if fools playing the fool got a lesson in respect (and maybe a little instant punishment) from time to time.
