There's no point in debating these people in private, there's especially no point in using excessive statistics in your talking points. A better idea would be using the kind of tactics you would see being utilized in The Hammer of the Patriot where you "debate" them in a public form and slam them with emotional arguments. I've had a surprising amount of success by using their the watching audience against them in tandem with emotionally charged and punishing techniques. It's alinskyist as fuck, but it works.
A lot of these people are the people that cannot stand the idea of alienation and having the dunce hat very vocally forced on them in front of people. Dominant arguments, even emotional, beat the hell out of trying to use statistics and justifications for your views. As dirty as it is, Alinskyism works now that these gun-grabbing fucks are establishment.
The right to self-protection is inherent. There is no inherent right to speedy travel. And remind them here in the United-fucking-States we believe in inherent rights. Government doesn't give us shit so it also can't take away our rights out with absolute due process. And full artillery pieces. A Privateer asked Congress if he could use the cannons he appropriated from enemy ships. They told him he didn't even have to ask. Until they were banned everyone who had the money could purchase what the military could in terms of small arms as well. Call them an authoritarian fascist and unamerican, they don't believe in freedom or liberty refer to number 1&3 refer to 1&3. They are unamerican cucks who don't understand the foundation of the country. Tell them they need to learn history and read the thinkers and philosophers who founded the nation.
