A "Blowhard" is not a derogatory term per se... Unlike the like the term "Limey", which derived it's origins from the Royal Navy and then became a term that was considered derogatory...

I kinda like giving some of the members a "goose" every once in a while when they repeatedly make posts that appear to be condescending and blowhard-ish, know-it-all-ish...

IMHO that is part of the process, to moderate posts that are mis-information or antagonistic...

If you disagree, perhaps you should take a look at all of his posts and determine if there is anything useful aside from a diatribe or counter point...

If I offended anyone, I sincerely apologize...
