when we say that A is B, we generally do not mean that A is strictly identical to B—which it clearly isn’t. This applies even when we say things like 2+2 = 4. Obviously, “2+2” and “4″ are not even close to being identical.
This seems to mix up labels and referents. 2+2 is strictly identical to 4. The statement “2+2=4” is not the same as the statement “‘2+2’=‘4’”

The referent of the label 2+2 is strictly identical to the referent of the label 4, but the labels 2+2 and 4 themselves are obviously not identical.
