What does any of this mean? In what way is Popehat (a law blog and accompanying Twitter account) a “petty dictator”? What “filth and corruption” are we talking about?

I get that these are all things that feel good to say but I don’t think it’s out of line to ask for actual substance here.

What corruption and filth?

Agreed. Popehat got Trump deranged. He went off the deep-end so precipitously it wasn't funny.
