If possible, look into their family tree. If crypto, you can most likely an ancestor that could possibly have been jewish based on their name and where they lived at that time. For example Bill Gates; https://files.catbox.moe/ym4cpe.png There are also many jews who pretend to be Christians. They might profess to be followers of Jesus, they might look and sound White but what content of the bible do they focus on? Many crypto-jewish Christians focus mostly on preaching the old testament, their most beloved figures are usually old testament figures and they usually name their children after old testament figures as well. Then there are crypto-jews who like to pretend that they are 'jew-wise' and on our side. They might criticize the jews and even condemn them. These individuals however are usually very over the top, they say stupid shit as ''We need another holocaust'', or ''we need to gas the jews''. They will sneakingly perpetuate the holohoax lie. These jews also like to focus on one aspect of the jew question but not on it's entirety. For example; they'll have no problem exposing the jews who have power in the West but they totally ignore the jewish rule in the East. They would like to have you praise someone like Jew Putin as an ally and even Communist China. Also these jews will always get triggered if you criticize any terrorist action against the Palestinians.
