Not sure if that was sarcasm referring to labeling of Biden as socialist by Trump and co?
Because I doubt any real socialist would consider Biden a socialist.
And I think you can infer Orwell's position enough from this essay itself - he is concerned about "the liberal tradition" being the last bulwark against worldwide fascism just one sentence before criticising England's liberal tradition for not being willing to actively stand up to evil because that tradition believes good will win out because good is good. Liberalism is hardly sufficient, but it's necessary.
(Another way of putting this: Orwell is not an accelerationist. You can see from this essay that he's quite concerned with the material conditions of the working class in a realistic way, and the idea that they should get worse so that the people will revolt is neither convincing nor appealing to him.)
On the other hand, despite the fact that my tongue was firmly planted in my cheek when I wrote it, such Debbie Wasserman Schultz haters as Nathan J Robinson and Noam Chomsky have adopted the 'Vote for Biden and keep protesting' angle so who's to say how the real socialists are voting this year?
I doubt Biden would last as President until Inauguration Day.
Thankfully, all signs are pointing to a DJT victory tomorrow! ;-)
