That means if we are to play with raw facts, that it is either a raw fact, that other people do some thing differently than you. Or that it is not really real as it is a real ontological negative like say evil.
Here is an example of raw facts and really real negatives:
"Logic
¶
All thinking is a process of identification and integration. Man perceives a blob of color; by integrating the evidence of his sight and his touch, he learns to identify it as a solid object; he learns to identify the object as a table; he learns that the table is made of wood; he learns that the wood consists of cells, that the cells consist of molecules, that the molecules consist of atoms. All through this process, the work of his mind consists of answers to a single question: What is it? His means to establish the truth of his answers is logic, and logic rests on the axiom that existence exists. Logic is the art of non-contradictory identification. A contradiction cannot exist. An atom is itself, and so is the universe; neither can contradict its own identity; nor can a part contradict the whole. No concept man forms is valid unless he integrates it without contradiction into the total sum of his knowledge. To arrive at a contradiction is to confess an error in one’s thinking; to maintain a contradiction is to abdicate one’s mind and to evict oneself from the realm of reality."

So here it is for coherence: If everything is coherent as an added up positive as you also claim, if I recall correctly, then I just have to say no and then I am a real ontological negative outside raw facts. We are playing what it means that the universe is orderly, logical and what not.
That one is not particular to Ayn Rand. It is the folk belief that only positives are real, because negatives don't make sense.
I learned many years ago, that the idea that all of the world must make positively sense, is falsified by doing something differently and then listen to how that is a real, really real negative. The joke is that you can't observe a negative empirically.
