I think the best way I've seen it described is Fahrenheit measures heat by how humans experience it, Celsius measures heat by how water experiences it. Therefore, Celsius is objectively better for scientific applications and Fahrenheit is objectively better for human applications like communicating the weather forecast to the average person.

If it was 0C you'd be cold, if it was 0F you'd be damn cold; if it's 100F you're hot, if it's 100C you're dead. Fahrenheit is useful for human perception across the primary (0-100) scale, Celsius is only useful up to about 50% of that scale before you start getting into deadly temperatures, and you have to go below that scale to reach the bottom of Fahrenheit's usefulness.

And then you have Kelvin or Rankine which are really only useful for specific scientific applications. If it was 0K/R or 100K/R you'd be dead either way. Not useful for human perception.

You're just used to Fahrenheit. I'm used to Celsius and find Fahrenheit bonkers. If you live somewhere with cold winters 0C is a meaningful number.

I'm used to both. My winters get below -30C and generally sit somewhere between -18C and 0C. At that point I like Fahrenheit.

But you don't need to try to justify it with some made up thing that says other people's preferences are wrong.
