As for the trifecta, I can't help you out on "lynch mob", I'm afraid, but how about this for McCarthyism?
"The [tech industry] is infested with [sexists]. I have here in my hand [2] a list of [102] -- a list of [user]names that were made known to the [Github administrators] as being members of the [sexist majority] and who nevertheless are still working and shaping policy in the [tech industry]." [3]

Believing men and women are equal is "sick" now? What a strange notion.
Bertrand Guilladot and Louis Debaraz come to mind.
Anyhow, that completely misses the point - that witch trials were based on a presumption of guilt against which no defense could be made. Much like the way certain media sites attack people.
BTW, I'm disappointed that only "witch hunt" (terrorism against women) is used in this particular thread so far. Where's "lynch mob" and "McCarthyism", to round out the irony trifecta? (Hilariously sick when men liken themselves to women, whites to blacks, and capitalists to communists.)
