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.)
Yeah sure, I'll "shut up" about ICE so the libs in my life don't feel alienated
That one I'm not too knowledgeable enough about but I'm under the impression it makes a lot more sense to call for abolishing ICE as a real political goal than abolishing the family or the police
my politics are abolish everything up to and including linear time. the only salient question is what order we get around to it.
Please start by abolishing me.
I'm so tired.
under the dictatorship of the proletariat, /u/corgiwithalaptop will proceed to wither away
My contradictions will be resolved and I will disappear like sand in an hourglass
