re: the social media point, it’s true that the loudest voices on it are invariably the worst (something equally true on the left, right and centre) but it is used by governments and media to push the same sort of opinions they put in print so often.
re: the second point, yes that would explain why a lot of the commentary is risible but not why it is so uncritical or even supportive, in fact them all being English graduates should make that less likely if they are behaving honestly.
As an example, look at this report on BBC News’ site:
The health secretary reassures frontline staff that efforts are being made to get them the equipment they need.

An English graduate from a public school who went to Oxford or Cambridge should know exactly what that headline is doing. It’s a disgrace, not least to the memory of Hercules.
