Pretty confident in my solve. The only ones I didn’t get myself were 20-down, 29-down (obvious in retrospect), and 21-across (inferred the word, but didn’t know the tool).

To poor for vegetables, lentils, beans, grains, and tofu? Meat imitations are currently expensive, but aren’t at all necessary.

Maybe it’s a reference to the phenomenon when a word repeated that way isn’t noticed, or an earlier meme that uses it?

Just because it’s always said doesn’t mean it isn’t sometimes true. Can’t you think of examples of views that were fringe but became the moral baseline?
