The Alberta Christian support for forced sterilization is a case in point: Why on earth did anyone think that social Darwinism was a reasonable fit with Christianity? It can’t be, and the original social Darwinists were hostile to Christianity for precisely that reason. But, of course, some social Darwinists ingratiated themselves with Christians to gain influence for their policies.

Generally, Christians depended on social Darwinists to do the primary research about the lives of the poor, and then reacted to their carefully staged* horror stories out of sentiment and zeal rather than information and reflection.
