> You uncritically examined the diversity activity
Your post assumes that the people running the organization are capable of critically examining diversity and inclusion related matters. Sometimes, people are best off acknowledging that something is completely outside of their area of expertise, and deferring to the advice given by specialists. I certainly do this very frequently, when it comes to advice given by my doctors or lawyers.
If you wish to critically examine any and all advice you come across, more power to you. But you don't get to call someone out for being prejudiced when they are literally following the advice given to them by specialists who are trying to promote diversity and inclusion.
> There is a large difference between deftly running an activity like this and horribly running an activity like this. The undertones of the original post is that this was handled poorly.
There is no details or explanation in the article whatsoever, providing support to the conclusion that the activity was run horribly or poorly, and not simply following the exercise instructions given. I would hope that here on HN, people would avoid jumping to conclusions based purely on conjecture.
