Good! Do you know how we promote diversity? Always hire the best person for the job, no matter what. We've ended up with a pretty diverse group, as a result.
It's pretty rare that people set out with something other than "hiring the best person" as their conscious aim. I'm not making any comment on your workplace, but if this worked as a general strategy, there wouldn't be a diversity problem in tech.
Diversity quotas explicitly enforce something other than "hiring the best person" as their conscious aim. I think the diversity problem is exacerbated by this type of thinking as much as refusing to hire a <insert gender, race, religion, nationality here>.
