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.

look was farcically awful to me, and it was rich how the usual "historical accuracy" 
enforcers were silent about it. I've even gotten some people claiming that "we can't be sure" how vikings really had their hair done up but I highly doubt they had the equipment to maintain that look while raiding even if they knew about it and wanted to. I know it encouraged a lot more chuds to pick up the look, too.
You taught us a couple months ago that vikings looked like
Better chance of that than
and I stand by that.
I'd like to imagine a viking using some Flintstones-ass clippers filled with bees or something to even attempt cutting their hair like
I still thought it was better than the imitators that have followed it, just because most of them are from the perspective of the demon english
Jesus Christ, my sideburns are an inch or two away from looking like that. No wonder my barber dialed it back on my faux-hawk.
I knew about the likes of spencer and robinson popularizing it in late 10s, but goddamn
I think it's really just men with that hairstyle
I haven't seen it on many women, but now that I think about it, it might look cool and comrade potential is unknown.
It's usually fashionable lesbians so
i wouldn't say fashionable, maybe in 2015. and its definitely no longer a queer thing, every white women and their mother had an under cut ten years ago.
Any haircut that looks like something you would’ve seen 100 years ago
