I don’t know what to do, you guys

A lot of activists are trying to effect some actual social change. That requires not staying on the basics forever, just as if you're writing papers on operating system design, you won't be spending much time explaining what pointers are. Even in a classroom, a graduate-level class on operating systems isn't a place where you'll be taken seriously if you complain that pointers are needlessly confusing. But it would be a mistake to conclude that coherently explaining pointers isn't important, just because nobody working on OS design seems to do it, or that the student wasn't earnest in finding pointers needlessly confusing. In fact it is absolutely fundamental that pointers are taught well and students be taken seriously when they express confusion -- but it is precisely because it is fundamental that it needs to be in a separate place.

I have seen two good forms of "101 spaces", though. One is quietly listening in upperclassman spaces, the Internet's venerable rule to "lurk moar". You won't understand everything at once; you certainly won't pick up the lingo, and you probably won't understand several of the conclusions. But in an era with internet search, you can slowly work on figuring out what people have found out, just as it's possible to catch up to the state of research by just reading papers and trying to figure out what they mean.

The other is friends, people who have been through the 101 class but also personally know you're acting in good faith. If you say something that's innocently wrong to them, they'll know it's innocently wrong, and not malicious, badgering a tired point, concern trolling, etc. In turn, of course, listen to what they have to say.

But besides those, there's certainly a lack, and for various reasons, a lot of people may not find internet-lurking their style of learning, or may not have sufficiently knowledgeable friends to go bother. It would be a good thing for the world to see more. But unfortunately, the responsibility to create them cannot be on the shoulders of the activists. If you think teaching at a research university is ever half-hearted, imagine what it would be like if the researchers weren't paid to teach, weren't expected to teach at all, and were, often, trying to fit in research in their spare time after another full-time job.

As one example, my father, an anthropologist/historian in his 60s who spent his whole career and life befriending, interviewing, translating, and writing about indigenous rural peasants in southern Mexico, and probably knows as much or more about their history and circumstances as anyone alive (in an intellectual sense, if not precisely as lived personal experience, since he was never himself a destitute peasant) was told by a 30-year-old recent Ph.D from a well-off family (who had literally never worked a job outside academia, and spent her entire life living in rich US suburbs) that he had no right to comment on the circumstances of indigenous rural peasants, “the subaltern” to use her term, because he he was a privileged member of the hegemonic class, whereas she could, as a Latina.
