It would be useful if people carefully considered their real motivations for their feedback, and whether it was really all correct and relevant. Feedback which hasn't passed a strong internal filter for whether it is basically constructive, objective and well-informed isn't worth voicing and really should be withheld. So I like that you say "be thoughtful."
Yeah, I'm a big proponent of the thoughtfulness you describe. I don't like it when people shroud rudeness & cognitive miserliness as "just calling things like they see them." I prefer "See it, think about it, then call it."
I really value honesty, but not every emotion-laden thought that passes through our heads deserves airtime.
