You're right that I overlooked your second point. My apologies.
What I was trying to get at in the second half of my last sentence is that when minority groups on a campus express a desire to create their own organizations, whether to promote a specific culture or to simply create a safe place, I'm inclined to believe them that they feel it's necessary. As a middle class straight white male, I feel as though I can't wholly understand the pressures, both positive and negative, that spark the creation of such clubs. But if African American students, for example, say that a Black Student Union is necessary for them to feel safe, supported, etc., in their academic and college/social endeavors, I'd rather trust them than mistrust them.
I do agree that ideally we'd be able to find a way to strike a balance by celebrating diversity without a need for groups like this, but I think they still serve a purpose in getting there.
