There’s a lot more to diversity than the liberal/conservative ratio. I could come up with any partisan divide to argue anything I want, e.g. economics academia has very little diversity because the ratio of communists to capitalists is 1:100, or philosophy academia has a lot of diversity because the ratio of liberal feminists to radical feminists is 1:1, or something like that.
