Always bad strategy to pretend you know what someone thinks about an issue after dead. Just gives more credit to the method of discrediting the message because of defects with the messenger. Good people come up with bad ideas and bad people occasionally have good ideas. Sticking with the merits of the argument is always the best method . Wasted breath on defending a eugenics advocate who should be taken seriously because she stopped short of race. Stick with the benefits of birth control. A pretty easy argument.
