why historically black colleges?

[inca nitta]

I just noticed that there is going to be another Equality Ride and the list of the proposed colleges to be visited are historically Black colleges, such as Spelman and Morehouse.

I don't understand why these particular colleges are on the ER's visiting list, because as far as I understand, these colleges do not expel students for being gay, unlike others.

Here is something from Spelman's handbook, which identifies what is an inappropriate conduct:

4. Actions Against Members of the College Community
A. Physically or verbally abusing or threatening any member of the College community.
B. Violating Spelman’s Sexual Harassment Policy or harassing any person or group of
persons.
C. Actions against oneself and/or displaying behaviors that could endanger self.
D. Sexual misconduct or unwanted sexual behavior that involves actual or attempted physical
contact of a sexual nature.
E. Fighting, regardless of level of responsibility.
F. Disruptive behavior or disorderly conduct.
G. Engaging in obscene, lewd, or other conduct that disrupts any program or activity on the
Spelman campus or impedes the freedom of movement of any member of the College
community (including all College facilities and off-campus College sponsored events).
H. Any discriminatory conduct that has the effect of creating a hostile environment for another
member of the College community based on race, disability, gender, religion, nationality,
age, or sexual orientation.

It looks precisely that Spelman discourages antigay discrimination on its campus, thus it is a gay friendly college, so why it is important for Equality Ride to visit them? I can definitely understand why it is important to visit Liberty University, but I can't understand what's the deal with historically Black colleges, like Spelman and Morehouse?

Can somebody, please, explain it to me.

Thanks,

Inca.
