I don't think anybody deserves to feel shitty for doing important work for free. My problem is when the insults are personal, and not about the code. Even good

I don't think anybody deserves to feel shitty for doing important work for free. My problem is when the insults are personal, and not about the code. Even good coders produce shit code at times, you need to tell them when you see it, and they need to tell you, that's what reviews are for. But you don't need to attack them personally.
