How the fuck do you get to your 30s in America (or anywhere honestly) without learning that 99% of "debates" are worthless. I think I learned this as a teen seeing "Creationist vs athiest" debates. Really solidified in college when I spoke to people (including one who was on the Alex Jones train "early" in ~2014/15) and I realized no matter what I said they seemed to not understand. Had the exact same experience talking with a Scientologist, and realized that me/my family/friends were doing the same as christians. Just straight up not engaging and getting mad everytime anyone brought up anything that couldn't be easily thrown away.
IE: you can just lie. You can just refuse. If your "opponent" doesn't realize or doesn't call you out, they are immediately on the back foot. Even if they do, then you "logical fallacy" them. Debate is worthless unless you know the other person is interested in learning. Like, I've seen some "debates" here and on reddit and elsewhere online that are at least somewhat meaningful. But these guys already have won by you engaging. There people aren't stubborn or don't understand. They don't want to change, on purpose.
Like I guess cover your ass, but if I were him, I'd at least couch it in "Kirk engaged in a dangerous game of courting right wingers that are unstable and prone to killing anyone they think "betrays" them." But of course, Hasan does the same shit. Engaging with weirdos (and not the good type, like us), so he's afraid of the same. And he should be, but maybe don't wander off into the swamp if you know gators are out there, brother.
For American, I agree with Alaska, Zinn is a good start. Critical reading of lib sources can be ok. (IE, Ken Burns' general messaging is off, but its a decent overview if you can read between the lib brain)
This is the first book I read about Taping. That was like 10 years ago, I don't really remember how well it was all presented, but might be a decent start. Written by a Yale guy in 96, so it might be a bit... you know. https://archive.org/details/godschinesesonta0000spen/page/n3/mode/2up
