I'll start. Fahrenheit is the superior temperature system for weather reporting. We should use metric for literally everything else, even Celsius for cooking, but I'll be dead in the cold ground before I abandon a system in which you actually get to experience both 0 degrees and 100 degrees. Freezing being 32 instead of 0 is literally the only downside, and it's not a hard number to remember. I'm prepared to die on this hill in the comments.
This is why we need re-education camps
