"Shorter Brad DeLong:
We'd be better off if colonial subjects had put off their nationalist aspirations for a century of so."

I posted that in comments and it was gone within an hour.
Pedants aren't unintelligent, they're just mediocre minds who prefer clarity to subtlety and who proclaim their preference as the one and only moral choice. The sin is pride.

And again: "All I did was point out that you're criticizing the moral logic of nationalism as such. Is that why you removed my comment?"
This time less than half an hour.
