Well ok - we now can discuss what "touching" can mean. I meant it in the standard everyday meaning i.e. to objects "touch" each other. In reality the nucleons won't do that though...
The standard everyday meaning is based upon the perception of how two things come into contact and interact. Again it makes no sense to look upon this as two objects not actually touching each other, the interaction is there. It's just how it works on a sub-atomic level.
