gollark: That's back to just sounding weird and arbitrary.
gollark: I see.
gollark: It seems vaguely like complaining about food having chemicals in it, which would be very stupid, except there is apparently decent evidence of "processed" things being bad, whatever that means.
gollark: It kind of annoys me when people complain about "processed" foods because they never seem to actually explain what "processing" does which is so bad or what even counts as "processed".
gollark: Also, you apparently didn't hide anyone else's faces. That's probably impressive, though? I mean, I don't have context for such numbers, but they seem big.
