It is BadEmpanada, who I mostly know from his videos debunking PragerU. He is a non-American who routinely criticizes America though, which gives people a cause to demonize him thoroughly.

Though I think most recently I saw him clowning on Vaush for outing himself as a pedophile that is also into bestiality, which seems to have riled up the kind of people still holding onto Vaush as an example of ideal internet politics.

So overall it seems like he has a decent trajectory calling out grifters.
