That he was a liberal who “once loved” the Democratic Party means he was already irrational to begin with.
It was just a salad of anti-SJW tropes and anti-left hysteria.
What should be concerning is that the sort of things said in this video, the hysterical anti-left outrage mongering and whining about some imagined anti-white oppression and the “extreme left” taking control of the media and political parties, is that until a few years ago, these were fringe tropes of actual fascists and similar reactionaries and ethno-centrists.
And now it’s mainstream.
As an actual radical leftist, who is painfully aware of how impotent and insignficant the left actual is, it’s troubling that the sort of authoritarian technocratic capitalism espoused by an organisation like the Demcratic Party, and corporate owned media like CNN and MSNBC, is somehow conflated with anything I think.
This fool may be right to “walk away” from liberalism. It’s just a shame he appears to be walking right into something much worse.
