I don't think anybody's offended by your stance, just that we feel it's a weird hill to die on. I'm a scientist, so I use Celsius and Kelvin all day. I've switched my home's thermostat and refrigerator to both display in Celsius since my brain is already in that mode. It would be easier if the whole world standardized on something instead of it being split like it is, and since science has standardized on Celsius, that standard for everybody else should be Celsius.
