Whether one thinks that discrimination in hiring is justified to offset suspected discrimination in other areas is besides the point. The point is, there exists discrimination in hiring that results in women and URM candidates getting offers that would not have been obtained were it not for diversity status. The opportunities of people categorized as diverse in tech company interviewing is substantially different from those not categorized as diverse. Maybe I'm biased towards the SF bay area, but there's a palpable mismatch between how common and prevalent these practices are and the offense people take when they're acknowledged.

I'm not sure why you think what I'm saying is different. At my company, white and asian male new grads are only given a chance to interview if they're CS (or math, EE, or other tech majors) grads from top universities like Stanford, MIT, Carnegie Mellon, etc. Candidates from boot camps, less well known universities, or non-tech majors are only extended the chance to interview if they're diverse. Does that mean that a diverse candidate from a boot camp who gets hired is unskilled? No, probably not. Does it mean that a diverse candidate from a boot camp would not have been hired if they weren't diverse? Yes, because non-diverse candidates from boot camps don't get interviewed at all.

Maybe I'm biased toward the SF Bay Area, but the mismatch between the prevalence of these policies and the discomfort with acknowledgement of their existence is concerning.
