Please don't. It's off topic, against the site guidelines (https://news.ycombinator.com/newsguidelines.html), and generally stops being true after awhile. Instead, just give a corrective upvote and move on.
Something like this is pretty obviously necessary at this point; it is trivial for me to find examples of bad-faith downvotes that cannot be backed up with argument, and it shouldn’t be.
Would forcing them to make bad-faith arguments really improve the place?
I completely see your point though, I just have a different POV. That's OK, we don't have to see everything eye to eye.
