Replaces all utterances of "Devil" in "Devil’ s Advocate" with literally "Hitler" MRA hate-nerds, rape apologists, latent racists, mansplaining art bros, with a twinkle in their eye they say "we'll, If I may just play Devil's advocate for a moment..." Begrudging, yet selfless, public defenders assigned to take up the case of the very incarnation of evil all for the patriotic duty to due process in argument.
But something inside you says "Ummm, He's the DEVIL. He probably doesn't need yet another lawyer going to bat for him." But suppose he does? Then surely Hitler deserves a good advocate or two here and there as well.
With this extension you can automatically change all instances of "Devil's Advocate" with "Hitler's Advocate" and do your part to give Hitler a fighting chance in the court of public opinion.
