I'll give you the same answer as the celebrated man in the street: what I see here is wagon circling. And the form it takes is trying to 'de-platform' (a modern term I don't really care for) someone who even suggests the notion that we should take a look at what we're saying and that maybe it doesn't reflect as glowingly on our own righteousness as we think it does. As I've said before, I'm racist. It's the era, location, and general environment I grew up in. And the only way I've found to combat that is to constantly work to understand that, where it comes from, and that is an illusion that doesn't have to control my actions. Because of this, I think it's always a good idea to welcome people who challenge our perceptions of ourselves. Being defensive and circling the wagons is just intellectual laziness to me. I bet you didn't expect an article for a response, Mike.
