I've read your piece, and unfortunately the overall tone sounds like a rant. I'm sure it wasn't your intent, but tone is hard to convey in a purely textual medium sometimes. I fall victim to this often, and have been actively working to try to avoid excessively negative tone (even if I feel that way).

The ranty tone of the piece obscures the rest of the points you were trying to make - many are good, but a strong tone will immediately put people on the defensive rather than trying to open up and understand what's being said.
