I read it as "shooting down" implying low-effort "I'm going to kill this because it makes me uncomfortable" type responses, not legitimate critique. Well-calculated rejection is indeed a valuable skill, but also hopefully won't come across as "shooting down".

It's tough to write any article about any part of this topic, because there's so much nuance and the nuance matters. Yet none of us would read a post that captured the nuance, it'd be way too long and probably cover too much that is obvious. (But maybe now I'm shooting down someone who might attempt to write such a thing... please do, it's worth a try!)
