Reminds me of when Douglas Crockford got removed as a keynote speaker because he made other people uncomfortable because he used the term "gonads" and also did a muscle flex when talking about WeakMap vs StrongMap.

Those weren't the reasons. For example, you make it sound like he just used the word "gonads" once, but actually, he had an entire 39-minute presentation with multiple references to testicles.
