I am just truly curious as to how organizations would be different if "southerners" would mind their own business, or whatever he was espousing.
Back to discriminating against pnm's - as an old lady whose seen alot over the years (and not just in greek organizations), there is discrimination based on just about every ridiculous thing you can think of when it comes to offering membership to an organization. I've even seen discrimination in Bible study groups (no lie). So, to say that because a national organization has something in their charter about "non-discrimination," they are going to abide by it, is generally a bunch of bull hinky. And, this is not exclusive to the south...
But, I've become quite jaded over the years
