As I understand it Damore did seek out feedback from smaller groups of people before releasing it company wide but even if he didn't, who cares? It's very common to publish documents to the entire world asking for review. That's what the RFC processed for digital standards is, that's what arXiv does for academics.

You are the one being disingenuous with this inane critique of the specifics of how Damore sought out feedback for his ideas. He really did do that, he really sought out criticism and continues to do so, you didn't take it wrong though... you're just critiquing it in an inane way. If you disagree with his points, then engage with the points. If the way in which it was written is so deeply flawed then it shouldn't be hard to refute them.
