It's not my deal to determine what's "worthwhile" or not to the eye of the beholder, but yes, beauty pageants are sport (in my personal definition).

For the record, I'm not trying to convince anyone that my definition of sport is the only acceptable definition (although I think that some definitions out there are way too narrow, I do acknowledge that mine is rather broad). With regards to your comment, I was just trying to highlight the difference between 'competition' and 'sport'.

I just feel that excluding activities like Chess and Cheerleading from "sport" is a bit too narrow for my tastes. Regardless of whether or not someone has a personal interest in said activity, other people obviously have a lot of interest in it... and "downgrading" their organized competition based on subjective parameters is a bit unfair.
