(In any case, it seems clear from what [RichardKennaway] wrote that he doesn't himself identify as progressive, and his description of progressives' thought processes doesn't appear to be the result of a serious attempt to understand them sympathetically.)

I confirm that this is accurate.

And I stand corrected that the virtue of newness in progressive thinking has got old, while the word "progressive" persists. What do they think of "progress" these days? "You can't stop progress" was the saying back then. I haven't heard it uttered seriously for a long time, and if it's said at all, it's more likely to be as a criticism of the opposite side by imputing it to them. First relevant Google hit here.
