For me the easiest tell is the up front, unprompted, and unsolicited declaration of nonpoliticalness. When someone takes the time and expends the breath to announce how nonpolitical they are, what follows is almost always a rant about how everything/everyone else is too political these days, and that of course leads into something between status quo advocacy and outright reactionary/regressive sentiments for some fabled time before those wicked politics were visible to the nonpolitical ranter. 
People that are hostile to service workers. Some just want to take some ideological stand against tipping when the service worker doesn't really have a choice and needs those tips to survive in the current unjust system in a way where ideological purity gestures toward that service worker just look like being a greedy and sanctimonious asshole. The worst of such people will actually declare, shamelessly, that they believe that service workers don't deserve a living wage. The implications of that are 
worthy.
I may get shit for this, but I'll say it anyway: this hair and beard combo, seen on living people. 
I have yet to meet anyone in person with that look that wasn't a chud.
(If one of you is a comrade with that look, I am sorry in advance for the prejudice and if I ever meet you in person I will atone by buying you a drink or something.)
i would love a podcast but most of my knowledge comes from googling binges at 3 am. I start with something like "precolonial africa gay" or "real african queens" and let god take me. I read this really great book about african kingdoms from the library a few years ago but i cant remember the name.
googling "precolonial africa gay" is already really illuminating and i've only just started.
i'm looking at this and there are so many promising terms to google in it https://daily.jstor.org/the-deviant-african-genders-that-colonialism-condemned/
anyway thanks for pointing me in this direction, it's fascinating
that was a beautiful article! im glad i now know about victoria especially and will be looking more into her. I also really love when historians dont ascribe modern eurocentric terms like transgender to non white history.
