So what argument are you making when they are acting with insufficient information and there isn't yet sufficient information to come to any actual conclusion? If it's anything other than "we don't know yet / I don't know, and neither do you" that's not grounded in reality. "I don't know" is a perfectly valid statement, but it happens a lot that people favor something definitive if flawed. That's a problem when "I don't know" is ultimately accurate, not abandoning nuance, and using language that anybody can understand. But that is essentially what the comment you replied to was saying when you said nuance isn't relevant.
I'm not saying anyone is too stupid to understand. I'm not using willful ignorance to imply an inability to understand, but rather that they simply don't know, and don't care to know.
