I regard this as a hostile work environment, being subjected to it.
I attended a few of these mandatory “training” sessions while working at a large defense agency in St Louis. I learned to keep my mouth shut. There is no upside to saying anything. They always state that the training has a non-attribution policy. That is not true. If you challenge anything in the course your bosses will hear about it.
I hear ya! When I was working we had annual training for a couple decades about what constituted a “hostile work environment.” Then the leftist HR departments started doing things that really pissed me off and definitely constituted a hostile work environment. Being close to retirement, I kept my mouth shut and head down.
The whistleblower at Sandia is one brave person.
