A new comrade with a lot of energy and creativity has joined my organization. It is a joy to work with them and they add a lot to our work. However, they have years of critical theory academy time in them and it makes it difficult to discuss politics...because I do not understand anything they say. I am seeking advice on how to handle this constructively. If I am alienated speaking to them, certainly the community we work in will be too and I want to avoid that situation. An emblematic example is below:

For instance, we were having a good conversation about disability activism and suddenly a switch flipped and they entered jargon mode. When I told them I did not understand they got very apologetic and seemed hurt. I do not know how to proceed.

There have been a few similar instants and now I am starting to dread when they raise their hand. Clearly some of the issue is in my reaction, too, and I am trying to work on that. Any advice is appreciated!
