Common ground exists, but that doesn’t mean someone is immune to criticism.
Yes, I do believe that ancaps would throw people out of helicopters. Not only has that actually happened but generally they think it’s funny and keep saying it. I take it so seriously that I had the last guy who said it to me banned from our mutual social organization after breaking his arm. In self defense...but that’s just my take. I am sure others have more grace and tolerance about that “joke” then myself.
While the burden of proof is on the individual making a claim, their is no requirement for a person to teach another. That sucks but part of personal responsibility is cultivating a understanding of your environment and the culture you’re exposed to. You can’t effectively fight to change a thing if you don’t understand it.
I honestly don’t know why someone would call you a Federalist, but that’s probably my own ignorance at work. Like what did you say?
