I don't even know how to start this or frame it so I'm just going to say the interesting part.
This little blurb feels similar to the thing that opened my eyes and set me on the path to leftism (Amerikkkan military intervention in central and south America). Like it sucks that the author came to Mr. Thach with the ignorance, but it's a really good reply. Maybe the follow up is deciding to be a shitty person about this information, but this part seems neat.
