I also agree with your point around phrasing. I agree that lot of people took away the wrong meaning due to the phrase "lower the bar" (which is a very loaded phrase). This piece probably could have been better received if the author sought out proof-reading with trusted co-workers and friends beforehand. In particular the author should have:
* Dropped the awkward and monolithic generalizations of "Left" and "Right" at the beginning.
* Stayed way the hell away from talking about biological differences, just say that men and women have different preferences for working hours, fields, etc. and don't touch on possible causes.
* Don't emphasize on the benefices diversity initiatives have on diverse candidates, but rather the possible negative effects for the group as a whole. The point about OKRs contingent on hitting a certain percentage of diverse team members turning hiring and transfers into a zero sum game was actually a really good point that potentially hurts diverse groups themselves by limiting cross-team mobility.
* At the end, don't try to turn this into a Conservative vs. Liberal issue. Just point out that affirmative action is not nearly as uniformly supported as people make it out to be. For reference 42% of the population opposes affirmative action for race in the workplace, and 33% for gender [1].
