I think you’re a little off the mark here. Specifically you’re confusing what is (reality) with what ought (ethics).
Let’s look at an actual Paladin defender post:
This doesn’t strike me as someone who is disconnected from reality. He directly says Paladins are better than other classes. What First is disconnected from is ethics. He’s saying that Paladins should be overpowered — he might not use the “over” part, because of the negative connotation, but this is a clear case of Paladin supremacist thinking.
It’s not that he’s seeing a different reality than you. It’s that he sees the carnage and smiles.
