Same as you. I agree on Fahrenheit on the same principle, but it's not that big of a deal and °C isn't that hard to adjust to.
You get used to what you use. When people tell me F I have no idea what they are talking about. I hate when my car or home reset to F after a power outage because they display gibberish. Is 68 a good inside temp? I know exactly what to expect for C.
This is true, but Fahrenheit is directly based on climate norms (though thanks to global warming there's an argument to be made for recalibration). For F, 0 is as cold as it typically gets most places, 100 is as hot as it typically gets most places. By that metric it's a useful measure for climate temperatures. For that purpose, measured temperature norms make more sense than the freezing and boiling points of water.
From what I've read, that's only a story that it was based on climate temperatures in his hometown. According to the story phycist Daniel Gabriel Fahrenheit defined the 0 and 100 degree points of his scale as the highest and lowest temperatures regularly observed in his hometown of Danzig, now Gdańsk, Poland, then later when he needed to recreate the 0 point of his scale he came up with a brine that stabilizes at a specific temperature.
What we do know for certain is that the brine existed, was made of water, ice, and ammonium chloride, it did indeed stabilize at 0°F, and according to a letter he wrote the scale was based on the Rømer scale, but adjusted in magnitude so he could make 32 divisions between the brine stable temperature and the freezing point of a regular water solution, then 64 divisions between that point and what he observed to be the normal human temperature. The reason for 32 and 64 divisions was that since those numbers were factors of 2, they would be easier to divide linearly between their respective upper and lower bounds.
Fahrenheit observed that using this scale water boiled at roughly 212°F then after the popularity of the Celsius scale some 50 years later redefined his scale so that it kept the original freezing point of 32, but now had 180 divisions between Fahrenheit's boiling point. This kept his existing scales fairly accurate to the new definition (the upper bound which was 96°F was now measured to be 98.6°F and the lower bound of the brine was 0°F now measured at 4°F) and used the new convention of defining the scale by water while keeping some nice number of divisions between their points, although they are a little more arbitrary now than they were before.
