I'll start with one that doesn't seem directly related but correlates so closely that I can't help seeing the "tell" as a warning: putting "kappa" in a sentence like a punctuation mark. I've never seen an online conversation that started with that tell and didn't wander into final solutions and 14 words if it went on long enough. I know it's a :freeze-gamer: thing but it's not like there isn't already a wide overlap between :freeze-gamer: and :frothingfash: .

Also if someone goes out of their way to make it know that they’re not racist/LGBTphobic/etc (“so I was talking to my friend who’s GAY the other day,” the rest of the story has nothing to do with them being gay), spend enough time around them and you’ll find out they actually are
Similarly, some of the grossest male sex pests I have ever met (Joss Whedon/Louis CK style "jerking off in front of someone uninvited isn't a problem unless the audience is too prudish") had to announce, unprompted, that they were feminists(tm)(r)
So hilarious/disturbing to hear old conservatives mention a black person's race whenever they are brought up in conversation. Especially American Southerners ofc. Like they'll say it if it's a positive comment to be like "hey I can have a positive thought about a black person, not racist btw"
