What niffweed does
not do - certainly not as a typical trait - is to look past what people are actually saying, and try to look at the supposed hidden motivations for them to be saying it. Niffweed may refuse to talk to individuals; but if he does discuss something with them, he will address their arguments as given.
I challenge anyone here to give an example of niffweed acting in the way several people (with whom I agree) have described Cyclops as often acting, that is, arguing not the points someone is making, but the supposed motivations for them saying it.
Actually, niffweed tends to the opposite extreme. If people make arguments - as in, typings - that are poitically motivated (as in, made to agree/disagree with someone else, or to put someone down, etc) it takes him a long time to conclude (much less assume) that that's the case, by which time he is likely to have lost respect for the person.
That is the precise opposite of Cyclops's behavior.
Now, one can say, if they so wish, that one is Gamma Fi HA, and the other is Delta Fi HA, or whatever (I obviously don't think so); but let us not say that their behavior is identical or even similar.
On a personal note, I like niffweed's style of seeing some individuals as good people, and others as assholes; by contrast, I find argumentations based on "what your real reasons for saying that are" extremely irritating.
