As an addition to the "I probably couldn't get a job as an academic these days" file comes this link (via @roddreher) to a University of California San Diego document requiring a written statement from faculty applicants:
The Contributions to Diversity Statement should describe your past efforts, as well as future plans to advance diversity, equity and inclusion. It should also demonstrate an understanding of the barriers facing women and underrepresented minorities and of UC San Diego’s mission to meet the educational needs of our diverse student population.
Some faculty candidates may not have substantial past activities. If such cases, we recommend focusing on future plans in your statement. However, please note that a demonstrated record of past effort is given greater weight than articulating awareness of barriers or stating future plans. A more developed and substantial plan is expected for senior candidates.
I suspect "none" would not be an acceptable answer. I also expect a detailed discussion of how one has tried to promote intellectual diversity within the academy by resisting the left-liberal hegemony would be even less acceptable. Just as well I'm not trying to get a job at UCSD.
