Well, yeah, Bateman is /fa/, hard to see him as anything but that.
He used things like clothes, his skin, his vocabulary, his décor, etc, as a way of manifesting his own existence. It was not real to him unless it was in the category of the superficial and easily manipulatable. He wielded select traits like an artist, to push a narrative about himself that wasn't true while at the same time being the most honest, real thing about him.
This is because, at his most basic configuration, being a psychotic character, he did not want or need to partake in material concepts; he did so only as a way of justifying his existence and personality. This is proven by hew arbitrarily set are his lines of defense; he could have killed that other dude for any reason, but picked the business cards and used it like a great excuse without even realising it. Those business cards threatened not only Bateman's place in society, but society's place in his insane internal landscape. Who was he if no one was looking at him?

The idea that one does not exist unless they are being perceived is a socially inherited trait. And the whole idea behind being /fa/ or not is whether you use the lifestyle to cultivate and extend personality as a way of perceiving your own existence. It's a form of art like a lot of other things. Bateman isn't /fa/ in the sense that he experiences fashion and lifestyle like we do, however, he actually *is* /fa/. The two concepts are inseparable.
