Further investigation shows the site owner, James Lindsay makes his entire living being an activist against gender studies and critical race theory. There's an extraordinary amount of resources dedicated to pushing back against the Robin Diangelo. Having heard her speak and having read at least a bit of her book, most of it is showing white people that all the things that we've tried over the past 10, 20 years are clearly not working. There's little improvement in inclusiveness in traditional white/male dominated cultures, such as the engineering teams at FAANGs for instance. Its insisting that you do something actually about it rather than patting yourself on the back for doing what you think is the right things. It takes a great amount of twisting about to ignore the main points, and all of the writers you linked have done so.
What you call the "dogma" of dealing with a racist culture I call people lived experience. Its heartbreaking to me how very conservative-minded and flat out defensive on issues of inclusion and race the HN community has been when the subject of race is allowed to be a thread.
