Maybe I'm just old, but I want to focus on engineering outcomes, not "trolling." If that means "can't take a joke," that's fine, but also "haha I'm just joking" is often what people use to try and hide behind their actual intentions.

I don't even work on Rust anymore, and in fact started this thread with a criticism of Rust. There are lots of good criticisms of Rust. There is a difference between "this criticism isn't good" and "every criticism is an offense."
