A lot of people diss NASCAR because they really don't understand what's going on.  The same can be said for F1, hell... for lawnmower racing if you want to stretch it.  
I used to think NASCAR was pretty boring, but then I actually sat down and watched a few races.  The racing is one part, but there are some pretty cool stories to follow with the drivers, the tracks, etc.  There is a HUGE amount of strategy going on when you see them "race around in a boring circle".  The strategy is almost as cool as the racing itself.  ...and as for being from Georgia or the south giving you the "right" to make comments... considering that a LOT of the top drivers are from 
California now, I don't think that holds water.
NASCAR road races are fun to watch.  They used to be kinda silly, because it was obvious that it was a "fish out of water" experience for most of the guys.  Now... you've got guys like Robbie Gordon, Tony Stewart, Dale Earnhart Jr, etc.  Those guys *know* how to run a road corse.  Hell, Boris Said, a famous BMW road racer... is now running a 10 race deal with NASCAR!  
NASCAR doesn't have the technology that F1 does.  By that, I mean they don't have the in-your-face technology.  I'm sorry...but "launch control", computer-assisted paddle shifters... and constant telemetry streaming to the teams.  ... technology is great stuff, but it almost seems that they've put so much into the cars that it's a computer battle rather than the drivers and the cars.  You may mock NASCAR for it's "low-tech" approach, but they run carburated, push-rod engines that you gotta shift yourself.  
I guess what I'm trying to say is that it's just a different form of racing.  Don't knock it before you understand it.  You may not like it, and that's fine... just please be a damn adult about it (or a pre-adult) and voice your opinions without flaming someone.  Over the past 10 years I've watched message boards of all sorts, and there's a definite trend here.  People are complete jerks to one another at the drop of a hat.  Would you say it to them if they were standing right in front of you?  Probably not.  If you would, you're either a punk or just an asshole.  The world needs neither.  
C'mon guys.  I know I'm no angel, but quit being jackasses.  This is a good forum, and it's obvious that there are a LOT of Gran Turismo fans out there.  Let's keep it about that and celebrate the differences we have.  
(soapbox mode off)
And you snowmobile racing guys suck.
