Consider the source ...
I recommend taking every fact-claim with a block of salt, except for the statement that another child, Hana Williams, was killed by child abuse. But, contrary to C & L's claim,
the Williams werenot following the Pearl's teachings in committing the abuse that killed Hana.
I'm not defending the Pearl's teachings, nor condemning their teachings. I've not read their book, and don't know enough of them to comment on their teachings more generally. I'm just pointing out that C & L's piece has at least one fatal flaw their guilt-by-association argument.
As for, "We have also heard testimonies from numerous homeschool alumni ...", really? Who? Did C & L really verify that each person they spoke to - assuming they talked to any at all - had actually known the Dolezals?
I've heard enough false accusation @#$% from Christian-haters to be reflexively cautious, and when I see false fact-claims, guilt-by-association arguments, and annoymorous "sources", very skeptical.
But, seriously. For the sake of argument, I'll stipulate all C & L's claims of abuse and etc.. How does that change the simple fact that Rachel Dolezal lied (and committed fraud?) and lives a grand lie? I find the, "She shouldn't have gotten caught!" argument particularly unconvincing. This is just a pathetic attempt to divert attention from Rachel's lies.
