Just don't go away for the reason you stated. An insulting or demeaning PM is always upsetting, but gee, you still have a lot to contribute here, and to learn here. I'm a complete nimrod on this forum, and have seen a bunch of pretty un-american statements made from time-to-time, but, all considered, this is a great forum.
In addition, it's a very international forum, and even though I live in Texas, I can certainly learn a lot from those folks outside the USA & Canada if I listen with an open mind.
So please reconsider and stick around.
I don't wanna lose a fellow bluesman!
