License, no.

... but it makes for great legal cover.

And that's all this training is about: legal cover. One of many kubuki theatrics one must engage in as a corporate drone.

This is just the following orders excuse, but with more institutions participating.

As much hay is made of "just following orders" being no excuse, one sees it made so often because it does work, depending on the context.

(In a sense, it even worked in the Nuremberg trials---basically everyone tried was executed, but the entirety of the German army and the civilian populace who supported the Nazi party were not, even though they, too, were "just following orders").

It would be more honest if they all said, "we weren't thinking."

I think they would have even been acquitted on the charges of criminal conspiracy if they used that argument.

Surely you don't think they went through the trouble of having this diversity exercise in order to encourage discrimination? This is a case of someone who's trying to reduce bigotry being stupid, not unethical.
