Several commenters have chalked the author up to basically being a privileged incumbent waking up to the existential crisis of watching one's privilege being slowly taken from them and trying to figure out a way to stem the tide. Do you see it as something similar and therefore it doesn't really make sense to engage or lend it any legitimacy?
It seems a lot behind the opposition to this guy is based on people's assumptions about his motivations. OP or anyone else willing to weigh in would be appreciated.
