If one wants to be exposed to people from different backgrounds, one should go live in a big, metropolitan city / travel the world while earning his way. Sucking down enormous amounts of public / donor / endowment money to run social experiments, whether in university or otherwise and then using weasel-words like 'diversity' etc. is of questionable value, at best, unacceptable at worst...

Why should the taxpayer or the wealthy donor be fleeced to provide zero value to the unwitting student (who probably doesn't have enough maturity to make decisions independently anyway)?
