"Hate" might have been the wrong word to use. Point is all the QBs I mentioned had serious conflicts with their coach as did positional players at one time or another. Check out the Bill Walsh - A Football Life documentary and you'll better understand my point.
Saying i'm "fine" with it is not accurate. Bill's behavior towards his players never won him congeniality awards but it is not without decades of precedent as many NFL coaches had the same approach towards their players.
What you seem to not acknowledge is NFL coaches throughout history cull from a library of psychological approaches to motivate players. Bill was no different than Landry, Shula, Noll, Walsh, Jimmy Johnson, Coughlin, etc.
