Because someone, maybe not you, and maybe not me, but
someone would find a way to take this disclosure as slagging off the organization in question. THAT'S what I meant by greek unity/greek spirit.
Some people might care, even if it was 106 years ago. Some people really don't give a rip, and are only interested from a historical standpoint. And there are others -- and we all know people like this -- who will take any mention of unsavoury history and turn it into a personal attack against their organization. So, to keep the waters calm, I think it's best not to say.
But that's just the peacemaker in me, I guess. You're welcome to disagree.
