Linear,
Nothing is uncivil about our discussion.
That being said:
IMO
The subject was about teaching hitting.
If you feel you have something to add - put it out there.
If folks disagree - defend yourself.
Shoot - I do it all the time.
Just defend yourself without the negative personal stuff.
If you know what you are talking about - most people will see that - or at least they will be exposed to something new or different IMO.
But when you get personal - it all goes in the garbage.
JMHO.
