The answer seems to be no.
No matter what shocking things happen to people as a result of the excesses and evils of the Left - they do Not respond by reassessing the fundamental assumptions that led them to be Leftists in the first place.
Sometimes they become a different (more bitter, cynical) type of Leftist - but almost never do they abandon the ideology that has scapegoated them.
I say this based on personal knowledge of a pretty large number of the people (friends and colleagues) who have experienced high profile Politically Correct witch-hunts over the past few decades.
(So many - because I have been both an evolutionary psychologist and an intelligence researcher, and these are the most-often Left-persecuted groups of people over the past half century.)
This lack of learning should give pause to those who suppose that 'if things get bad enough' the masses will 'come-to-their senses', and 'see-through the lies of Leftism'.
Chances are, though, nothing that could happen will ever make a difference; because Western people are incapable of learning.
...Unless or until after they have experienced a spiritual awakening and become Christians.
And not necessarily then - because Leftism is so deeply, multigenerationally ingrained (perhaps especially in the UK and France - who invented this plague).
Plus, they are addicted to the delusory hope of The Sexual RevolutionTM, and the idea of surrendering their personal day-dream is intolerable...
So - if people are ever to abandon that which will destroy them (body and soul); they need to do it For Themselves; it will not be done To them; it must come From Within.
