You have a constructive idea here but sadly I think youtube will soon degenerate into shallow click-bait channels as there will be no other way in to get the required audience.
The ones you mention are not that relevant to people outside Canada, but I would be interested in hearing more about the Marxist infiltration of school system from Bryton Cherrier (your number 4) as this I see to be the main source of social discord and malaise today: The grievance politics from the loony left!
