Primarily for those who don't already have a discussion group. We started a few weeks ago, and this week's text is Mao's "On Contradiction".
You can join the group at #reading-group:genzedong.xyz
(an encrypted room), either through the GenZedong Matrix space (see this post) or by asking for an invitation in this thread.
It won't require intensive reading/listening; it should be doable for anyone who works or studies full time. We're currently following a study plan from China, but we can add recommended texts (decided by vote)
I used the link to get into the chat on Matrix
I don't know what "In Defence of Marxism" is, but it's not related to the discussion group. As stated in the post, you need to either ask for a direct invitation here (which includes posting your Matrix username), or join the Matrix space as described here
