What if I aim low? Like, "please include the letter c in your next commit"? Will that hit hard enough? Or should I go for a whole word? Come on, I need this!
The problem is that everything you've said requires actually knowing the person and their actions. I see people making massive assumptions to justify their hatred.
I think jokes and empathy can be somewhat orthogonal. In fact, I think any stable society/org requires a court jester. But dang, the amount of dehumanization, lack of empathy, and sometimes joy, I see is really scary. There are some angry, empty, people on the internet, that I hope to never meet in real life.
