The Definition deliberately enforces non-discrimination. The point of that is to make sure that licensors don't "color" the tool by putting restrictions in their license (thus excluding some potential licensees).

Surely you can see that this has no logical bearing on whether any given tool has inherent "political color". Some tools, like some foodstuffs, could conceivably be inherently incompatible with particular religions, for example. The OSD doesn't take any position on that possibility because it's not regulating the nature of the tool, just what the license contains.
