I don't actually think its a bad thing to monitor diversity in terms of race, gender & sexuality. An imbalance could indicate discrimination or discouragement of a group or lesser access to the education required for a job, particularly in the case of race & sexuality. 1/2 https://twitter.com/MrSonicAdvance/status/975647475938811905 …
I don't even know the laws on this in my own country, tbh. I'm less interested in whether it is legal to discriminate on immutable characteristics than whether it is ethical to do so.
