yeah we had a big problem with my new member class when I was coordinator - the sis mom was very homophopic, and the sis dot had openly gay friends. Sis mom said some very derrogatory (sp?) comments and the dot blew up at her....yeah that wasn't fun.....
My sis mom is my best friend now, she was my maid of honor at my wedding and my little one's godmother. Not to mention we work at the same place and live at the same apartment complex - yeah its sad

It truly is terrible when the mom dot thing doesn't work out, but its awesome when it does!! other sororities big sis little sis system probably has the same problem that the mom dot system has. I agree there needs to be unity though
