Alignment is extremely specific: it locates a creature on a matrix invented by Gygax for purposes other than being a behavioural descriptor, and not a great deal more.
The second claim also is equally true of alignment. If a red dragon is Chaotic Evil does it love its children, or eat them as they hatch? Does it detest Vermeer's paintings, or admire them? Does a Lawful Good gold dragon ever spy on people, or does it always announce its presence? Does it make sentimental choices or abstractly impersonal ones?
I can't even tell, from the alignment descriptor, if the red dragon will admire the swagger of the adventurer who boldly confronts it, and let her pass - or rather will fire breath her do death and be done with it.
