What are you even talking about?
Edit: To clarify, I don't think 100% fatal medical advice is a good analogy for good-faith testimony relating to a "piping system that allegedly flooded a few local homes."
Maybe something more like "Hey I'm not a licensed doctor, but in my experience double-fisting twinkies leads to weight gain."
Are you referring to Donald Trump? (There, invoked.) He's a moron and there's plenty to criticize him on. Which is why it's bizarre to see this particular false[0][1] narrative thrown around so much even to this day. If you watch (TDS trigger warning; transcripts in [0][1]) what he actually said[2] and the immediate followup and clarification[3], we can definitely agree that he's not a great communicator, but I think that whole thing got taken out of context in a very dishonest way.
