Your statement ...
... is worded in such a way that you think a comment is directed at specific people. The concept of a message board is that all messages are directed at everyone, because anyone can read and reply to it. That's how I could get a "like" on the post you are complaining about.
On that basic definition of a message board, yes ... I can reply to any message without regard for who it was "directed to", because I can read it and I can express my opinion, which includes addressing misconceptions.
As for my "personal perspective", isn't every post here going to come from the poster's personal perspective?
What you call "condescending" has, in numerous other threads, been received with positive responses for clarifying misconceptions. As I said, people outside the business have made presumptions of how the business works and that causes inadvertent misstatements on their part. My personal philosophy is that the more everyone knows about how the business really works, the better the conversations are. (And yes, I am entitled to include my personal feelings that I wish I didn't have to explain as often as I do.)
I am truly sorry that you chose to take my remarks in a negative and hostile way. But your attack on me is not going to change my position about addressing misconceptions about the business I have made a career in for over a half century.
