Additionally, you could rephrase from "downvote" to "rebuttal", which I think makes it more clear that not only is the opinion/post unpopular, but that there is information that contradicts the OP's post. It could make for a more substantive phrasing
Slashdot has (had? Haven't used Slashdot for years) a reason for up/downvotes, coupled with meta-moderation where you would occasionally be asked to moderate someone elses choice of moderation.
Don't remember how well it worked.

Frequently downvoted reasons could be added to a blacklist that requires additional elucidation before being able to submit the downvote.
This has been an interesting thought experiment. I'd expect the results might besimilar to Robot9000: https://blog.xkcd.com/2008/01/14/robot9000-and-xkcd-signal-a...
