As for the UA SGA, I have never supported the Machine. When I was a student there, I fought against it, even ran for SGA Senate. The SGA first tabled a resolution calling on the Greek system to integrate. While I understand their irritation, given the fact that the system had already begun to integrate, it was a stupid PR move. The SGA later voted in favor of a similar resolution.
It is possible that we hear more about race at UA because it has such a large Black population, relative to most other schools, AND it has had a very proud Black Greek system for years now. The average income differential between the races also makes it difficult for the Greek system to take on the demographics of the entire campus.
