Okay I know I’m being a killjoy pain in the ass here, but about 54% of the US population reads below a sixth grade level, and a big chunk of those people are functionally illiterate. Making fun of people for poor spelling and grammar, even if the person you’re making fun of is a jerk, is mocking people for being victim’s of the US’s brutal program of systematically restricting access to education. And even if the person you’re mocking is an asshole, other people see that, and see a socialist making fun of people for being the victim of a shitty white supremacist system.

There’s also the whole thing where “correct” spelling, grammar, and pronunciation are middle class white spelling, grammar, and pronunciation. Dialect and accents are a big class issue mostly everywhere, but also in the US. How you talk strongly influences how people think about you, and what they assume about you - aka African American Vernacular English being regarded as evidence someone is less intelligent or less knowledgeable, or that they’re morally a bad person, as are a lot of accents from the South and from Flyover.

Plus, standardized spelling is an op by the dictionary companies to sell more dictionaries :wtf-am-i-reading:

Again, I know I’m being a killjoy about something minor, but there’s a bigger picture and it’s important. Literacy is one of our biggest weapons against capitalism and always has been.
