@dstark has it occurred to you that when people are told that theIr communities are going to have their names changed because other people say so and that they’re enabling “more crap to be done to black people” if they don’t support it, they might feel that those other people are attempting to assert control over them? Did you go to Yale? Did you live in Calhoun College? How many 'Hounies have you actually talked to? Are you so certain that you have the standing to tell them that their home is now to be renamed because you’ve decided it’s an"easy, positive gesture"? Do you really “have a dog in this fight”, when you assert that other commenters with different views from you don’t?
I know a lot of 'Hounies - who clearly do have a dog in this fight - and I will tell you that opinion’s far from unanimous on what to do here. It ranges from “of course you should change the name” to “hell no”, with a lot of nuanced positions in between (e.g., keep the name but hyphenate it with that of an African-American alumnus).
I thinks it’s reasonable to ask, given how our society’s views have evolved, whether a name change might be warranted and, in any case, whether much more should be done to ensure that Calhoun College becomes a means to increase the understanding of the Yale community and society as a whole about the pernicious and ongoing effects of slavery and racism, which John C. Calhoun certainly supported and enabled, his public service notwithstanding.
There could be many ways to do that, some of which could include keeping his name on the college while renaming parts of it, adding explanatory signage as to why and seeking to ensure that there’s an ongoing discussion about Calhoun, racism, slavery and Yale’s role and responsibility in enabling them all.
It’s also important to consider the precedent being created by renaming the college, or the other actions that might be taken, and the manner in which the decision is made.
Personally, I think Yale should take steps to educate all who want to participate in this debate on who Calhoun was, what he did, what he believed, the implications and results of his actions and beliefs, the historical context, how Yale came to name a college after him and Yale’s historical role with regard to racism and slavery. Suitably informed, the community could then have a meaningful discussion, consider the various alternatives and decide the right thing to do.
