I don't think the point of this system is to try to "weed out the people that [whoever] doesn't like" — it's to improve the social climate so that people can discuss things like reasonable adults, even when they strongly disagree, instead of  throwing insults at each other like a bunch of two-year-olds who aren't quite diaper trained throwing tantrums & the contents of what should be in their diapers at each other.

It's not to weed out people. It's to weed out childish insult sharing, in the hopes that maybe we can even learn things from each other even when we disagree. I like when people with different points of view can get together and talk, & sometimes even change each others minds.  But people don't often convince me of the rightness of their point of view if they're busy hurling insults.

Which is what the comment section used to be like too much of the time. So I welcome this new system, at least to give it a try. Time will tell.
