At the beginning of his speech, Boortz insulted every good teacher I had, and as a result insulted me. I couldn’t continue reading.
That's too bad, because you should have read it for all the bad teachers you've ever had (...and I might well be one of them!) Being informed isn't about reading only those things you like. It's reading the bad news, too. It isn't that you "couldn't continue", it's that you didn't want to continue.
