That's a little dramatic. First, phenomenological philosophy is some of the best philosophy one can read (highly recommended) and it takes the first-person perspective as its starting point. I hardly think that a small minority of people who are basically professional whiners are "civilization destroying" no matter how loudly they whine.

They can barely even win a handful of national offices in the ultra-safe districts. It's a tiny, tiny minority, even among left-wing voters (and I'd be willing to bet even among people who lean progressive), which is evinced by the fact that, in the US, we have a boring, middle-of-the-road President Biden and not a hardcore left-wing Bernie Sanders or, somewhat more mildly, Elizabeth Warren.

Annoying isn't the same thing as "civilization destroying" and we should keep that in mind.
