I have responded to your overly simplistic perspective, based purely on enrollment numbers, that Mt. P kids are somehow getting "the short end of the stick," by pointing out all of the other elements/options of the issue (opportunity to try out at Wando; opportunity to play other sports, such as lacrosse, which aren't widely offered elsewhere; opportunity at other schools; etc.).
I've pointed out that parents should consider the entire picture (quantity and quality of academic offerings) when criticizing a situation that, in many instances, they've constructively chosen for their children.
I look at interscholastic athletics at Wando, and I don't see a major issue based on enrollment. Nor would I have complained if my kid hadn't made the soccer team. I would have encouraged him to improve, try again, and/or try another sport or activity, OF WHICH THERE ARE PLENTY AT WANDO.
The enrollment/opportunity issue is legitimate in MANY ways. Athletic/extracurricular opportunity is not among them. That's simply a soapbox for parents who want to have their cake (arguably the best non-magnet public high school in SC) and eat it, too (see their kids on the varsity).
