well upon here? You posted it...and people replied to the content of your post. Your replies give the sense that you feel attacked for posting it, when the criticisms have actually been directed at the manner and substance of the content Mr Simon presented in his letter.

Some unsolicited advice...maybe provide some framing thoughts from the outset next time rather than just dropping the link. Starting with "Thought this was worth sharing not because I necessarily agree but because it represents some of the current criticism that's out there...." might have made it less about you, if that really is how you're processing the critical responses.
