I'd argue that 17 might actually be a fact.

It's a fact that Celsius is simpler. So unless you're really odd, it is much easier for younger people to grasp the concept of temperatures when described in Celsius instead of Fahrenheit. The way 17 is written makes it sound like it's an opinion being presented as a fact, but I think it really is a fact.
