Examples include: The "Brights", the "Rationalist" Societies, "Euthanasia" (translating to 'good death').
The "Intellectual" DarkWeb is populated by many examples fringe figures whose contributions are considered laughable in their own claimed fields, Stephan Molyneux being a complete joke in Philosophical circles but impressing his teenage and tech-trained audience is a prime example. Christina Hoff Sommers is another figure whose brand of feminism seems far more widely supported by people who've never taken the time to read a book by a single other feminist. Sam Harris's forays into Moral Philosophy and Free Will again do not find a sympathetic audience of any significant size among people who actually study these subjects and know much about them. Jordan B Petersen is an unusual case because his noteriety and audience is far more to do with his political statements (attacking trans people, misogynist comments, claims of a conspiracy of Post-Modern Marxists) that are substantially separatable from both his academic work (Maps of Meaning) or his weird self-help manual (even though this shoehorns in his conspiracy theorizing).
