@Blackgendermoderate The full story, from https://www.atlasobscura.com/articles/benjamin-lay-abolitionism-racism-slavery-dwarfism-quaker
>The snow protest was by no means Lay’s only performed, dramatic, nonviolent act of radicalism. Quaker neighbors of his kept a young “negro girl” as a slave, and continued to justify the practice, even in the face of his exhortations on both the evil of slavery in general and the “wickedness” of separating enslaved children from their parents. When the neighbors refused to listen, Lay invited their six-year-old son into the cave where he lived and innocently entertained him throughout the day. The boy’s parents panicked. The Village Record, a local newspaper, later described how Lay “observed the father and mother running towards his dwelling; as they drew near, discovering their distress, he advanced and met them, enquiring in a feeling manner: ‘What is the matter?’” The parents, understandably terrified, explained that the boy had been missing all day. Lay is said to have paused, and said: “Your child is safe in my house, and you may now conceive of the sorrow you inflict upon the parents of the negro girl you hold in slavery, for she was torn from them by avarice.” Taking the Bible as his model, he seems to have generated living parables to show people the evil of their ways. (Another version of this story claims that the child was a three-year-old girl.)

When I heard the word "kidnapped" I assumed it was more violent.
This guy was more based than I thought.
