> Who signs up for this?

It's pretty clear from your comment that you've made up your mind and don't want an actual response, but for anyone who is interested, I can give a real example.

I worked at an agency where the "leadership" was exclusively white, and the lowest paid roles were staffed by people who were mostly black. Licensed professionals were getting passed over for promotions in a way that left no explanation other than race.

Staff complained, and management (to their credit) wanted to address the concerns. So where do they go? To talks like this, etc.

You might think that racism doesn't exist and that there is no value in discussing how to fix it. For those of us living in the real world, these are useful resources.
