Let people express themselves without policing it.
Attitudes like yours create echo chambers of sycophants. I personally hate an environment where the only feedback allowed is positive-to-neutral. Negative things, like dismissal that you seem to hate so much for some reason, are feedback too.
Welcome to the thunderdome.
Be as brutally critical as needed but criticism should be something of value.
“Meh” is the equivalent to “neat”. It adds nothing, but unlike neat, it takes away pride.
Also if we’re taking the meta discussion, then you’re doing the same thing you’re saying not to do. People are just giving feedback , but unlike the original comment it’s constructive feedback.
And I didn’t merely say “Meh”, I followed up with some more text and added a new dimension to the discussion.
