Absolutely right.
Unfortunately the board(s) have become dominated by what you term "the hard core"; the rest of us have to endeavor to tune out the noise and still get what we can out of it. I originally began on boards back when Scott was still coach as a tool for information moreso than "opinion"; of course that slowly evolved into "pay" boards and "other," and I don't do pay boards.
I began attending with my father in the late sixties, became a grad in 76. My "crew" are guys I played football with back in the day, fellow musicians, church people, golf buddies, etc. I stopped listening to Kornblut way back when other avenues became available, but I agree with both him and you. The ones screaming for Tanner's and Muschamp's heads are definitely in the minority for now, and it also seems the more versed one is in the sport the less the level of "fire them and the BOT now". We all get angry and frustrated but we have also seen this movie many many times. We have a good feel for when termination is warranted. Now is not that time.
Hopefully the "noise" hasn't been sitting around recruits at the games.
