I’m rude to debt collectors who call me trying to collect debts from people who happen to once have had the same phone number as I once did. Like, I’m not who you’re trying to collect from, fuck off.
I’m also rude to generally any scam caller, they’re some of the few people I take great pleasure in telling off because I can get away with it. They’re scammy assholes, what’re they gonna do? Cry to the authorities? Knowing that they’re pieces of shit who scam people out of money? Good fucking luck.
Linguistic elitists—for example, people who shout that “the Blacks don’t speak good English” or who get pissed off that “I could care less” is an idiom that exists.
I was a linguistics major in college and, sorry not sorry, language is malleable and it changes over time. You can’t stop it. Look the French—the Académié Française can try to legislate the language all they want, but nobody says la coussin de sécurité, they just say l’airbag.
