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’m surrounded by people who watch local news, which is 99% “a criminal did something bad…but then our plucky boys in blue CAUGHT HIM!” It’s not enough that every other movie or TV show is about cops (or superheroes or cowboys or people in the space navy, who are all also cops). CNN / MSNBC / Fox News would honestly be an upgrade for people who still consume local news.
More often its, 'a criminal did something bad... we haven't caught him yet, so stay extremely vigilant, 100% of the time; you could be the one that finds him!' So people create the fantasy of being a vigilante and install security cameras all around their house in the suburbs.
I signed up for nextdoor because I'd heard it was a good place for fashwatching, and I left it after like a month because I couldn't handle how bad it really was. There would be videos of petty theft by kids, and the comments would be about how those children and their parents need to be put in a cage
yeah, you can watch the fash -- but who wants to know that everyone in their neighborhood is a fashy shitter?
This is slander against RDR & Django.
