For the record, I took you to be proposing a single counterexample with two components, rather than two separate counterexamples; I'm sorry for the misunderstanding.

Now that I know the second bullet point was meant to be a separate counterexample, I have a different objection to it: I am unconvinced that any implementable version of it would both reduce stupidity and increase meanness. (The most likely outcome, I think, would be to increase meanness while replacing more blatant varieties of stupidity with more widely spread lower-level stupidity.)

EDITED to add: Oh, one other thing. If it happens that (1) it was you who downvoted me and (2) you did so because you thought I downvoted your previous comment, then you might want to know that I didn't.
