Actually, he has some pretty good points. 
The idea of a dorm being devoted to 1 Philosophy is kind of a mistake. It really does breed short-sightedness.
So, by mixing floors that have various focus, is not a bad deal. 
And I have to say that I like the idea of mixing COmmunity College dorms with regular university dorms. 


OTOH, I will say that in 1979, I was in a dorm that as all women EXCEPT for 1 floor that was to be 21 and over men only. My roommate was over 21, but I was 18. Both thankful and sad that the residential manager liked me and allowed me stay. But, that led to both my most fun semester as well as why I flunked out of NIU. :)
So, yeah, far better to get mixes going
