The convention was in I think '67. We integrated at the next convention in '69. It passed by one vote. I've spoken with a brother that was present at that one (has gone to every Grand Chapter for like 50-60 years).
Other than the record I was not there in '69 or '67 to hear what happened so I can really say no more except that it was generally all of our Southern chapters that were for segregation. We're a Southern fraternity in origin so I suppose that would explain (not excuse) what happened.
As for Lott's comments at Mr. Thurmond's birthday party.. Well I'm a realist. I didn't hear anything about segregation... I didn't hear any pro-segregationist speal. What I did hear was Mr. Lott being very complimentary of his friend and colleague. Perhaps he did not take the time to think how his words might be (badly) taken out of context.
On a side note I heard Maxine Waters last night on CNN saying something to the effect that Lott was saying the same racist stuff that he had in 1948. Ms. Waters he was around 9 years old at the time
Tom Johnson (former President of CNN who was mentioned in the article) has gone on the record saying that he regretted his vote in '67. I'm certain Lott has as well.
This reeks of the media making an event out of a non-event. See Gary Condit.
