To your post I say... and listen good... Boooo!
You know, there are times and places when expressing your opinions are appropriate and by golly, the race track is certainly one of those places. We here in America love to hiss and boo those we dislike. In Europe, they whistle, but it's the same thing. Maybe that is being a poor sport, but so be it. It's one thing to boo someone, but it's totally another to act physically on it. That's why at the track, law enforcement will eject you quickly if you throw something, but won't do a thing as long as it's only booing. Now if you are around a bunch of drunken itiots, the booing could cause some physical reactions, but those bums should be kicked out anyway.
Love us or hate us, us boo-birds are here to stay.
BTW, there has been only one driver in the upper echelons of NASCAR that I've ever booed and that was Earnhardt the senior. I didn't hate the man, just always wanted to see him get beat by someone else. I was at the race where he died and though I earlier booed at him, I cried for him on the way to the hotel.
