As an ex-Redditor I do /s reflexively because I assume someone will always be offended. Welcome to the Internet, I guess.
Then just don’t write the opposite of what you mean. It’s not funny or witty or clever to write “Women should all just live in the kitchen, NOT.”
fuck em, that’s what i say.
if they don’t get it, sucks for them.
other tone markers I’m more likely to do tbh (/gen). some people do struggle to get certain things, and tone markers can help move communication along.

Something I notice a lot in asian languages is that the asian languages I do speak (Thai and Mandarin) are more situation dependent than english. It would be the listener’s fault to discern whether one is being truthful or sarcastic. I believe this is the other way around in most european languages. Bear in mind that this was something I learned many years ago, so feel free to correct me if I am wrong.
