Drupal developer here. I've worked on core, maintain many contrib modules, etc. and have worked with Larry IRL on Drupally stuff. I really don't understand what this quote is talking about if they aren't specifically pointing at his history. He's never been less than pleasant and considerate of others in my IRL interactions with him. Also, from his post:

> Second: I've been involved in the Gorean community since 2002. I've been involved in Drupal since 2005. It took until late 2016 for anyone to realize I was in both. Moreover, from what I understand from the CWG the first "leak" was someone on that alt-lifestyle private forum who found my account there, screenshotted it, and started passing it around.

I don't know where he has talked about race, maybe the master/slave comment is the one referred to but if you follow those links in the article to the actual posts he made you can see that what he wrote isn't that controversial, he's just not fully supporting changing the master/slave terminology or adding more options to the gender field of a user profile. The author of the article described it as "not agreeing with the SJW party line".
