It started early... https://lists.debian.org/debian-user/1999/04/msg00623.html
And here is a generally well-sourced summary: https://rationalwiki.org/wiki/Eric_S._Raymond
There is a general and valid concern in our industry about a liberal orthodoxy that makes it at least socially unsafe to express political thoughts. People who share that concern should have an even bigger problem with Raymond, who is an attention-seeking caricature of conservative or libertarian belief. People who have couched their bigotry in far more careful and subtle language than Raymond have found themselves ostracized from conservative circles, and for good reason.
I think the better way to engage with Raymond is on his manifest deficiencies as a professional engineer and technologist, and wouldn't want to start a rebuttal to his request for donations with his politics. But I also wouldn't want to let stand the idea that the opprobrium he attracts is rooted in orthodoxy or tribalism.
Do you have references to more information on that?
Lovely. To inject some psychological precision, only his narcissism can be considered a personality disorder. Being old, white, or male... no. Not yet.
It's possible to be an arsehole and not have a PD, and probably most arseholes don't meet the criteria for PD.
