Here is what I noticed about this, sorry if it is considered too off-topic:

There was an argument, about something specific and technical; It was refuted without singling out a specific person by name; without using humiliation or insults; using code to do so ("show me the code!"); and there was a polite acknowledgement and resolution.

This is an example of an interaction in a community that I think anyone would want to be a part of. Thank you.
