When I make coffee it is also right around 180-185F. I checked. I also scald myself with live steam once in a while so I know it's easy to burn yourself. I could cite some industry association's standard for brewing temperature, but I know nobody cares.

The point I'm trying to make is not that coffee should be hot, because I know arguing that is futile.

The point is, that framing this as a disagreement about readily available facts is incorrect and if you habitually interpret people's opinions/values this way, it warps your sense of reality to your own detriment.

I think anyone who wants to prevent me from getting hot coffee is not a nice or reasonable person, and I feel threatened by any implication that I would be in the wrong for making hot coffee if someone else spilled it. But these are facts about me, not about the rest of the world. As such, you don't have to accept them, but you can't invalidate them with facts about the world either.
