To be clear I am not arguing for or against working with a bunch of people from totally different backgrounds, demographics, etc. I am arguing that, because we can't do everything we should decide what really matters to us, commit to it in the long term, and invest in it to the exclusion of the many other completely worthy causes. I know it sounds obvious, but at least for the communities I belong to, the industry committed shallowly and as a result accomplished very little.
