It's easier to target your own than cacs. It's a diversion tactic I've seen from a lot of weak no spine AAs. Same ones going super hard on c00ns, but whine about Trump supporters and stay in the house, won't dare get into a flame war with racists over the computer where racial slurs and obscured statistics put them in a corner and bad mood which they're unable to counter argue. Sad really. It's like beating up a banter weight and avoiding the HW at all costs.
I prefer going at the cacs and ignoring c00ns. Cacs have an entire system backing them up, it requires far more attention and battling.
