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 had that hair/beard combo until I saw a picture of myself and realized I looked exactly like
A friend of mine told me "That's what dysphoria feels like"
Honestly, i get second hand dysphoria from seeing V*ush. It's just devastating how gross his deeply dishonest, simpy, chasery way of doing masculinity is. Everything about how that dude tries to be a man is just the most needy, most passively pushy attempt to get laid and it's just pure eeew and ick. Even if i was 4 more years into HRT and laser hair removal and would have perfect passing and spot-on makeup and hair game and all the guys on the street would go full
when i'm walking by being my goth gf's goth gf, a brief glimpse of 
would be enough to transport me back to the point where my egg had just cracked and i realized for the first time that i need to do all these drugs to repress that the sight of the stubble on my chin is slowly killing me.
There is a huge problem these days with vast numbers of white millennials looking like V--sh. I can barely go outside without running into these people. There is just like a V--sh Type of Dude out there that is very common, like a Ford Model T. I feel like a rebel pilot with a mustache in an x-wing screaming about how "they're everywhere, I can't shake 'em!" right before I get blown up.
Either that, or I just think about V--sh too much, even though I've spent maybe five minutes of my life maximum watching any of his videos.
