This is like crap I half remember her telling me about, idk if there's literally a Hungarian Jewish sect that believes the messiah was some guy in the 20s, I do remember her telling me about some weird Moldavian Jewish sect that owned like a whole neighborhood in Queens and did get in fights with other Jews constantly. But FYI there's been a lot of Jewish messianic climates, and a few besides Jesus still how followers today, or at least had followers until not that long ago. There's some Turkish dude in the 1600s who I think some tiny Jewish sect thinks was the messiah.

The Christians or Jesus's followers didn't exactly have an easy time in the aftermath of Jesus's death. Nowhere near as bad as the Holocaust though.
