> prefer debates be governed by [cherry-picked data] instead of whose argument is the most "humane"
There's a time and place for humane arguments and, in the absence of complete "data" (whatever THAT means), that may be all you have. At the end of the day, we're all emotional creatures and this often justifiably dominates considerations of human affairs. Not everything can be boiled down to problems in first order logic.
I'm trying to be charitable here, but it's difficult not to conclude that you're setting up the data as never being sufficient e.g. "whatever THAT means" in order to support humane arguments over data based arguments.
