That's an old argument that doesn't hold water. Sure if you misconstrue everything the worst way, you can convince yourself.

To pursue minority candidates who are qualified, is in no way discrimination. Unless you assume they are less deserving intrinsically, then it's fair to include them in a search.

Why would those candidates be excluded? Because white guys might suffer? That's a bankrupt argument at the core.

Fairness, the the privileged, looks like discrimination every time.

It's not about purposefully excluding anyone based on immutable traits, it's about not giving anyone preference based on immutable traits. The point is hiring people who are competent and can work together, "pursuing minority candidates" doesn't achieve that. I wouldn't want to be a "diversity hire" myself either, that's a bad position to be in, since everyone makes you feel that you are only here due to the policy, not because you have qualified in the proper way.

You are saying that seeking out competence will naturally lead to hiring people with varied demographics.

The comment you are replying to is saying that having demographic quotas is bad.

There's an implied disagreement about what is (what companies are actually in practice doing), but I don't see any disagreement about what should be.
