Syag,
I shared some of my experiences to provide testimony for discussions of most important part of Jewish life, education. Saying that my opinions are wrong because they are based on my experiences does not add much to the discussion.
Some of the value in that information is that some information comes out of the mouths of principals when there is a disagreement. So, you can assess whether this applies to your institutions without going thru the same painful steps. I absolutely do not think that all schools have these problems, or that the same schools do not have positive sides.
