Most of the Zizians who lived in Vallejo moved there from the Berkeley area. The reason they moved was because Curtis Lind felt empathetic and offered them extremely cheap rent. After not paying rent for years (despite at least one of them being an engineer at Google), they ambushed Lind, then tried to behead him and dissolve his body in a vat. Fortunately he was carrying a concealed firearm, so he shot them in self-defense, killing one. Three years later, Lind was murdered by another member before he could testify at the trial for his other attackers.

If there's any sort of marginalization by Lind in that story, I'm having a hard time finding it.
