“it’s wrong to be open-minded about 2+2=4.”—right, until you learn something about non-Euclidean systems.
It seems that you are talking about many things you don’t know much about.
Non-Euclidean is a term used to refer to certain types of geometries.
In this context, do you mean non-Archimedean? That’s very different. But then 2, +,4 and = will generally have different meanings. It seems pretty damn likely that interpreting these terms in say Peano arithmetic, that 2+2=4 is true.
