I’m totally on board with this. Most of this stuff is random culture crap I could take or leave, but common use of /s is practically an excuse not to make an effort to understand the other person’s POV.
Being a charitable reader and trying to understand the other person is everything.
Sure, without it there will be misunderstandings… But coming back and clarifying “I thought that was obviously sarcastic” is the kind of little nudge that makes both people reread what they wrote, and introspection keeps a community healthy.
It’s embarrassing when you misunderstand someone or if you didn’t get your basic position across - and frankly it should be.
And if people get nasty the second they see a bad take, that’s a symptom of being in an echo chamber (or at least a very polarized community)
