Ahhh, you missed the point of the thread. It isn't about the declaration, it's about the vacuum of the label.
Interesting point you bring up about labels, bear. It's not just true of labelling people, though.
Think about this: There's a part of your brain which has been developed solely for the purpose of recognising things. For instance, as a child, you see a confusing array of interesting squiggly patterns in brown with a smooth texture and a round knob on one side. One day someone tells you "that's a door", and from then on, anything that looks like that becomes a door. Later other descriptions of door get put in the same barrel under the same label. You need no longer investigate doors on any deep descriptive level, just check for the knob and the shape and your brain says "door".
However, it is possible to disable or at least relax that part of your brain. Some use meditation and other mental techniques. Some use yoga and other physical techniques. Possibly the easiest way is to take some shrooms or LSD. In the state thus engendered, you will find that the labels are less important and the things requir much deeper investigation. Once again you can look at that door and see the astounding level of detail in the markings that you would usually just dismiss as part of "door".
What you can learn from this kind of experience is that labels can blind you somewhat to reality. One doesnt look very closely at something when one already knows what category it fits into and can pin a label on it and continue with life. What you also learn is that those labels are extremely convenient. Without them life is overwhelming and time-consuming. A trip to the store can take hours, because every leaf needs close examination, as do the clouds, the pavement, and of course without any labels, one road looks much like another, and who cares which way you're going anyway? look at that pretty coloured thing over there....
All of the above applies to people as well as inanimate things
