The truth is that placing a man in the Monkey House was intended as an education for the public in Darwinian evolution.
“There can’t be any question about what they meant. Remember, this is a zoology class. Evolution is taught.”
Hammering home the lesson about “our own evolutionary history” was exactly the purpose behind displaying and humiliating an African man with monkeys.
It’s not, how shall I say this, an audience guaranteed to be sympathetic to a critique of Darwinism and its social impact, even one as thoroughly researched and accurately told as this.
