I could not agree more with the sentiment here. However, I don't see anything proposed to make it better?

Down voting allows bad values to flourish – and all , by definition - at the expense of love.

Downvoting is a double edged sword that solves some problems while creating others. I have not seen a better solution proposed. Downvoting is exactly what we use to not allow bad values to flourish - spam, plagiarism, etc. Like I've said, it's not without it's problems, but to just get rid of downvotes is not a solution, so what is the solution?
