Oh goody.
They should celebrate the birthdays of Hitler and Margaret Sanger, too since they are two of the racist b@stard offspring of Darwin.
Darwin wasn't a racist. Well, maybe mildly so by today's standards, but certainly not by the standards of his time. Darwin would certainly have to be considered less racist, for instance, than a widely admired figure like Abraham Lincoln who appears to have thought that blacks were inferior to whites, albeit only on average and that no discriminatory consequences should follow from this.
Darwin was also a more fervent abolitionist than Lincoln.
So would you lump Lincoln with Hitler?
