Copying and pasting my other comment:

Based on what they told me yesterday, they have started reading it, maybe a chapter or two in. Throughout my interactions with them over the last year or so, I have steadily gotten them to read Elementary Principles of Philosophy, “Tankies,” and now finally they have started Blackshirts and Reds.

Overall, they are your typical anti-communist “progressive liberal,” but in the last month or so have been pushing back against anti-Communism. This is genuinely a massive step for them IMO.
