It's really unfortunate that so many threads here devolve to bickering.
Having been in the middle of a few forum battles myself early on, I know what it feels like from both sides, and have concluded that it's just not necessary.
And it really stinks when it leads to a dad like Lion (who seems sincere and open ) threatening to block someone like coach2709 (who so many of us respect and have learned a lot from).
But with the caveat that I won't engage further, I think it's worth noting that the harshness that's so prevalent here wouldn't happen in person.
For example: Coach, as informed and passionate as you are about kids' health, I can't imagine you saying to someone, "So what I hear you saying is: 'You're OK with turning your son into a liar.'"
My guess is, as an accomplished AD, you'd find a different way of saying that.
I hope so, anyway.
