I'm confused. Why does it matter to anybody what any character is called? Seriously, I'm wondering this. People who call Ahsoka Tano (Fulcrum) FAT are obviously calling the character FAT because F, A, and T all appear as the first letters in her character designation. They are not calling this (fictional) character "fat".
I mean ... who cares? It's like the whole zeta character thing. Zylo or zKylo or Zeta Kylo Ren or ZKR ... call them whatever you want.
