Sadly, I suspect each "school" within the university has its own office dedicated to diversity. Mostly because they don't have much to actually do, so you can pack them with unqualified minorities in order to boost the percentage of non-whites on staff.
Anyway, to the extent that there might be any rationale for having an office dedicated to diversity and inclusion, it certainly should limit itself to, you know, addressing those issues within the school. It's thoroughly inappropriate for the office to spend its time on political issues that aren't remotely relevant to the school's diversity or sense of "inclusion" among its "diverse" folks. Shame on Harvard.
