You have conflicting logic there though Ben. You can't just go based off of what the acronym stands for.

SCISA has to be independent of "something"..that being the SCHSL..if I'm not mistaken. Also, if I'm not mistaken. Schools like Bishop England and Christ Church only have affiliation with the SCHSL in athletics..for example. They don't compete with public schools in Science Olympiad, or SAT competitions, etc... (i could be wrong about that)

Since these schools are first and foremost academic institutions..it's reasonable to presume that Bishop England and Christ Church are first and foremost..private schools..independent of other South Carolina High Schools..which is where the controversy is.

The argument most people have against private schools playing in the SCHSL..is that if they are first and foremost private/independent of South Carolina's public schools..how is it "fair" or what is the rationale for them being allowed to compete in a league designated for South Carolina public high schools (who to my knowledge cannot participate in SCISA).
