Personally, I think this site is over monitored. I belong to another discussion board which is very open to all opinions and I thin the only time a post is deleted is when someone advertises without permission or when someone is a scammer of some sort. Sometimes the discussions get pretty spirited and you sure can't have very thin skin with some of the threads. I find the threads which are of interest to me, I read them, interject if I choose to and I move on. Truly, i can't read them all nor do I want to!
All that said, I have total respect for admin, it's his site and should be run in the fashion fitting to him.
