Or some of us might have multiple sociology degrees and/or are in academia. But I’m sure if they wrote comments about Marx (or Weber or Gramsci or Veblen etc) you’d just assume they got it from wikipedia anyway. Though I’m not sure why that’s a bad thing. It’s not like it makes a difference whether someone read primary texts online or overpaid at the college bookstore. It’s the same information. The fact that anyone has a desire to learn, better themselves, and then try to use that knowledge is admirable and a service to society at large. More people should try it.
