Several years ago, I worked on some open source projects that involved Racket. The community and Matthew Felleisen in particular were very helpful, and it sticks with me that the project founder took time to teach me idiomatic/correct ways to write Racket code and tests.

Not condoning Matthew Felleisen's behavior towards Matthew Butterick - people deserve to be treated with dignity and respect - but there does seem to be a side to M.F that enjoys teaching and evangelizing Racket.

Felleisen's entire goal with the Racket project has been teaching-focused from the beginning. I don't think anybody in the community doubts that he cares about teaching and evangelizing Racket.

The problem is that he has a very... how to put it. Matthias seems to believe that you must fight and struggle your way through academia and prove your worth to earn respect at even the most basic level. He is known for verbally abusing his students regularly. As I wrote elsewhere, I was explicitly discouraged from applying to Northeastern if I didn't feel I could withstand certain kinds of regular verbal abuse at his hands. That's unacceptable behavior, regardless of the "true intent" underlying it.
