1. Reverse it. Call HIM a vile christian piece of shit 2. He corrects the record for you and says hes a jew because they can't help themselves 3. Everyone sees it and immediately understands whats going on. 4. Rub his face in it by calling him a self hating jew who makes jews look bad 5. tell him his behavior gives support and succor to nazis and he should feel ashamed. This barb works especially well because many jews were raised by their mothers, overbearing neurotic women as most jewish women are, and a key component of that is controlling behavior and shaming. Bonus - tell him you reported him to twitter and the ADL, and your "friend a mod is looking into your post history to see what other times you dogwhistled nazis." This plays on their natural paranoia. This is fine, because he could and would do the same thing to you. It pulls double duty because the boy-who-cried-wolf takes effect and destroys the believability of the "muh nazis" card, makes it hard to call you out (lol, claim you're a jew for good measure), and causes them to become even more paranoid and infight over "nazis sympathizers in the jewish community." All their worst fears are coming true: They shut people down so many times, for so long, with so many false accusations of nazism and "muh evil white man", over decades and decades, we came to believe in exactly the things they fear. And having no other avenue to express it without retaliation, we resorted to the very thing their paranoid mindset had them accusing every one of: hidden antisemitism, dogwhistles, and language games meant to destroy their public image as a religion and culture. Serves em right for being duplicitous malicious scumbags.
