That ... any deviation for an ideal is a necessary indicator of the eminent destruction of civilization is a prime example of snowflakecity.
The disqualification of a student's exam, by the State, for criticising religion may be a non-affair to some people, but to be concerned about it is not the same as believing it is one of the horsemen of the apocalypse.
The title of this thread starts off with "This week in the strange death of Europe:" To claim that Europe is dying because a mistake in grading a paper was rectified is about as hyperbolic as you can get.
The title is a reference to the Douglas Murray book, though it isn't specifically about the themes in his book. It's just a very evocative title. I use it in a general sense to refer to the gradual erosion of free speech rights in Europe and elsewhere in the West. Along with language policing, there is also language mangling, where criticism of religion is identified as 'racist', and to object to the use of that language gets you set upon as 'defending racists', 'xenophobia', etc.
I did not claim Europe was dying because a "mistake" (as if it were a clerical error) in an exam paper was made. The "this week in" is a suggestion that the dying is already in progress; that these events are evidence of it, not the start or cause of it.
