again with the assumptions about someone else's experience....
here is a fairly simple concept in social interactions that has proven to be maddeningly elusive to you:
a.) I don't spend all my time here screeching about my credibility on a given subject because I don't have to . People know me well enough (many in person) to judge for themselves the value of an opinion I might render.
b.) on occasion it's been pointed out that something I said was off the mark, whereupon I said "Sure, I can see that". (see point "a" above)
