I would expect no less from Carmel. I'd add '"hypocrisy" btw along with "pettiness".
In fact, one might drown (swimming titles being surfeit) in the hypocrisy - aside from the fact Carmel has LONG been the public version of Cathedral - who they also have long hated.
At least Cathedral is honest about just who they are (its not like they hide it) - without all the moral posturing BS....they simply want to win championships (ie. Basketball teams with no single CYO player to be found) and will find a means to accommodate that goal (find $ to pay tuition) whatever state you live in, color you might be or whatever "God" you care to worship....so long as you can help get that State Ring.
No doubt Cathedal would wait until 6'9", 30 points/10 rebounds per game "Beelzebub" graduated before they found an even distant need for a postseason exorcist.
With that, Carmel appears to love the lazy/easy/sad/DISEASED "trope" that somehow being a single geographic millimeter "North" of your opponent makes you somehow morally superior is more than sickening....and truly false. As someone who grew up in southern Indiana, it makes me puke a bit when Carmel even vaguely tries to use the race card in its favor. I've lived in both worlds...and lived North in Indianapolis since college...some 40 years ago.
I'd take Center Grove's ability and quite clear willingness to welcome people of different races, creeds and religions any day of the week over Carmel - push coming to shove....if Carmel is truly forcing me to choose.
