Let me see if I'm reading this correctly. Their logic is ...
"I'm going to sue the Outmeal, for pointing out how I was stealing from them."
"Now I'm suing various charities because somebody I don't like is giving them money."
1. The lawsuit is captioned Charles Carreon v. Matthew Inman; IndieGogo Inc.; National Wildlife Federation; American Cancer Society; and Does [Does are as-of-yet-unnamed defendants],
"And now I'm going to sue female deer. All of them! Do I even need a reason?"
That about cover it? Admittedly, I'm slight unsure about the last one, but it makes as much sense as the other two.
