I get your point here. It's important not to hold back and to be "honest". Being nice doesn't make the work better. I have met some people who take this as a license to not think as hard about how to formulate their feedback. So it comes out as harsh and personal, even if the kernel of feedback is valuable. Almost every "angry" feedback I've seen on the internet could have been rewritten to simply be good feedback. If you have the time to write and rewrite feedback, you can probably clean up arguments much faster. Taking a chill pill if you will. This is harder to do in face-to-face conversations, though.
