Where was this woke inquisition happening that you saw directly? I’ve seen people complain about this much more than I’ve actually seen it happening.
Perhaps it's a matter of perspective? Would you say e.g. James Damore was "cancelled", rather than being fired for discriminatory statements that an NLRB lawyer described as "so harmful, discriminatory, and disruptive as to be unprotected"?
Cancelling was never so straightforward as being fired. It was social ostracism and the soft understanding that no promotions were going to come their way, because the whole HR team was against it and their managers were never going to spend the social capital to fight that fight.
Their offense was objecting to a specific point being made in “implicit bias training”.
I was high enough in the org chart that I was privy to these conversations.
