The majority of students at SLU are white, middle-class Americans. There is also a large percentage of students from the Carribean islands, mostly due to the strong recruiting efforts of the school there. There is not a whole lot of noise from individual minority clubs. You may see some outside the cafeteria raising money for a cause or have a stand set up at some sort of event, but other than that, minority clubs are pretty quiet.
The student body, as well as the University's core values, are supportive of all sexual orientations, despite the school's strong Catholic ties. Yet the gay and lesbian communities within the student body do not have an extremely noticeable presence. Any gay and lesbian students at the college tend to fit in fine with the rest of the student body, so it is hard to see any barriers. No one is segregated at Saint Leo. In truth, it’s too small of a school to get too specific about who you hang around with.
