Of course - emotionally undermining valid criticism isn't just evil, it's also clearly against the HN guidelines and the purpose of HN, so even beyond it being wrong and manipulative, it just does not belong here.
> Don't be curmudgeonly. Thoughtful criticism is fine, but please don't be rigidly or generically negative.
> Please don't fulminate. Please don't sneer, including at the rest of the community.
> Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something.
All of these apply to both value-less critical comments (which I'm not defending), and to undermining valuable critical comments - therefore, "wow why is everyone so negative" posts are literally directly against the guidelines and have no place here.
