He does appear to be a solid person with good insights and reasonable reasons. The reasoning in his letter was different than the quotes or summary I had read. He did call it like he saw it and give the parents something to think about.
I admire his courage and conviction.
However, actually sending the letter as opposed to tearing it up (I have written letters to get something off my chest, but usually torn them up prior to sending) was foolish.
Personally, I will much better accept foolishness, when delivered from the heart that stupidity. He deserves the support of his community.
