Yes, we’ll, it was a real problem, but it was really just caused by a tiny number of people, almost entirely two. One really bad apple ... and all that — two in this case, but separated by many years, so the feeling had barely calmed down before another one arose. It could have happened in any community. For some reason it happened in Lisp. Shrug. Also, you need to take into account that Lisp has been in active use for over half a century!! A couple aholes in 60 years isn’t that bad a record.
