Just as any rivalry, a set of circumstances and conflicting personalities, have added to the lore of said “rivalry” and in turn, adds value to competition in sport.
This “rivalry” is no different than any other. There’s real “beef” in between fanbases at times. There’s even political backstabbing involved!
It’s makes sense to continue to compete in sports against the school in Oviedo. Better than not, in my opinion.
