It's another to have one respect you. Yes, we coaches tend to be tough on our kids. Sometimes we go overboard, and that's wrong. There is no excuse for it. But on the other hand, it is not our job as parents or coaches to make the world easy.
Baseball is a hard game, and somewhat dangerous.
To play it well at the higher levels requires a degree of competence, strength and toughness very rare in kids whose lives have been soft. We coaches are willing to sacrifice personal comfort for the rewards of baseball, or we wouldn't be coaches. Sooner or later, motivated players make the same choice. At bottom, most of them over 11 or 12 would rather be pushed than coddled. But I have learned, over the years, that parents just won't tolerate that short of coaching, these days.
