Simple, sufficiently accurate generalities start:
1. Almost any person who identifies as "Gorean" is into fairly severe heterosexual, male-dominant BDSM. (Otherwise they're misusing the term wildly, and it's not a common error to do so.)
2. Most men who identify as Gorean support society-wide male subjugation of females. Either that, or they are generally poseurs. (Otherwise they wouldn't bother using that term, and indeed would still be misusing it.)
3. Many people who engage in Gorean role-play don't identify as "Gorean" in real life, nor are they otherwise subject to the generalities in Point #2.
Basically, "Gorean" means a combination of:
A. What the BDSM community calls TPE (Total Power Exchange).
B. Strong opinions on how ANY woman should related to ANY man. (Or to any "true" man.)
Fuss about real-life Part B is a lot easier to justify than fuss about Part A, or of course than about a merely role-played version of Gor
All that said -- I neither know nor care to investigate the particulars of the case, such as: Was the guy just spouting noxious political views in a small group setting, or was he doing so more widely, or did his colleagues feel he was acting on those views toward them?
It might also be worth mentioning that a full set of Gorean views would include:
-- A strong set of professional ethics, different for different professions.
-- A "fuck you" attitude toward anybody who doesn't like how you conduct yourself in your private life.
