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.)
Thinking crime has gotten worse, it's an absolute TV talking point that everyone repeats nowadays. If you try to bring up empirical evidence of crime decreasing every decade they just respond with some anecdotal bullshit they probably made up. It infuriates me and I wanna shout their face, "facts don't care about your feelings".
I always reply in agreement then follow up about how imperial plundering of the global south has been increasing with the turbocharging of neoliberalism and all the criminal leaders and functionaries of the the US and its allies should be put in prison while letting everyone else out
I've gone the similar route and just acknowledge that all our business and political leaders are criminals, makes sense the rest of us are criminals too.
