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 did the version of keto where you just don't eat bread or sugary food. I think it was adequately sloppy enough to prevent any chudification
good for you, the keto comments are really rolling in and i am super triggered so i shall delete that part of my comment, no hate just cant handle it, it was my mistake i didnt even think about it before commenting.
cw death, mom, truama dumping, you dont need to read just explaining why im suddenly acting odd
spoiler
___ my mom died from a lack of potassium and heavy exercise that made her heart stop while on keto, she followed it the way you are sopossed to ate enough calories ect, doctors said it looked like she was "living in a third world country" she died of malnutrition.holy fuck i'm so sorry, from your reaction earlier today I thought you'd been on the diet
