Reddit mentions of Turning the Tide: U.S. Intervention in Central America and the Struggle for Peace

the danger is that the dude isn't accessible to rational argument. you could give him some homework, and if he does his readings in good faith maybe he'll change his mind. chances are your buddy doesn't think of himself as a racist, so maybe some basic understanding of history will help him out.

but again, probably he's going to feel very skeptical about this whole thing, so he's not really going to engage with the arguments properly. and the problem with wanting to attack things that are systemic is that sometimes you need to look at a large amount of evidence before you start thinking that there's a system pulling the strings.

i think the way people change their minds is by surrounding themselves with folks that have a certain viewpoint -- over time you begin to understand it much better than just by swallowing a bunch of books. essentially if all your friends think that X is a given, you're much more likely to believe X than if half your friends are desperately trying to convince you.

if he's starting to hate his job, and if he's starting to hate capitalism, then that's something that's directly accessible to him, that's something you can work with. stupid example: get him into street fight. they mostly talk about the pains of working minimum wage but it's from a clear left perspective, so they point out the way the system fucks black people whenever the subject does come up. more robustly, try getting him into left spaces (as long as he's not going to be a dick to others there). over time, he'll get to interact with racial minorities on the receiving end of this fuckery, and begin to understand that "hey, if all these folks agree with me that my boss is a dick they're probably on my side, so maybe i should listen to them about black people".
