I think there are two separate questions. The first is ‘Is the concept behind affirmative action valid?’ and the second is ‘Is the implementation of affirmative action effective, fair and just?’
I believe there shouldn’t even be a damn debate about the first question. This country has a massively problematic history with race relations and there are obviously still ripple effects in modern society, and we should take active measures to fix that. Minorities have been explicitly excluded from opportunities to gain wealth and status up until disturbingly recently, and many are still implicitly excluded from them to this day. Anybody who says that racism and the problems that come with it is a thing of the past is straight-up wrong. They are either not trying to understand the problems, or they are actively trying not to. Both of those are unacceptable to me.
The second question does merit some debate. Is it effective to simply say ‘if we have two equal candidates we’ll hire the minority’? How often does that really happen? Is it fair to do things like the NFL rewarding teams that hire a minority head coach? Is it just to implement quotas and percentages? I don’t have answers to all of these questions. I have some opinions. But as a straight white cis dude, I feel like my voice doesn’t need to be the loudest in the room in this one.
