Why so much shade from Arian on PFT

I do really like Arian and the way he thinks. But it feels like he gives so much shit and is so mean to PFT for no reason. PFT is always trying to be kind, fair to both sides, and not ruffle feathers, yet Arian can be a real dick to him and make fun of him being short and all that shit. Absolutely not deserved.

Anyone else feel that? Like, a ton of unprompted shade.
