M, not to worry. You didn't do a thing except participate in a very caring site. Nobody meant to hurt your feelins, if that is what happened.
I have been a member for 5 yrs and from time to time we get into lively discussions and some of us have strong opinions and think the rest should believe us (as if - chuckle here). Please bear with us when we do that. It's really just a sideline.
We know you are here for your son. We all come because of somebody - and for ourselves - and that's the reason for Valve Replacement site in the first place. The rest is just other stuff. And I am glad to know that you have participated in it, too. Just jump right in when you have a thought to share.
Blessins.......
