Ok, what do you do if your wife finds out as an adult that her mother was Jewish? Now your kids are Jewish too. Do you leave her and disown them? Does it change how much you love them?
Well, I can't speak for the excellent Mr Clown World, who I doubt has any Jewish ancestry -- but I would speculate that if he found out he was half-Jewish it might affect his plans for having children -- but nothing else at all. After all, truth is truth. If he found out that he was entirely Jewish, it would merely make him one of those exceptional Jewish heroes who exposed the crimes of their co-racials, like the extraordinary Benjamin Harrison Freedman: https://nationalvanguard.org/2010/10/a-jewish-defector-warns-america/

If you “find out” as an adult, you weren’t ever really one of them. They see you as goy
Such a person would be well advised to use a DNA test (even several) to see if the "discovery" is even real. If it is, see what was said about Fischer and Freedman above. I have known several people with partial or whole Jewish ancestry who nevertheless worked to fight the Jewish power structure that is now trying to terminate the existence of the European race.
