In passing, we should here recognize the difficulties presented by the idea of 'fit' and 'unfit.' Who is to decide this question? The grosser, the more obvious, the undeniably feeble-minded should, indeed, not only be discouraged but prevented from propagating their kind. But among the writings of the representative Eugenists one cannot ignore the distinct middle-class bias that prevails.
As an advocate of birth control I wish ... to point out that the unbalance between the birth rate of the 'unfit' and the 'fit,' admittedly the greatest present menace to civilization, can never be rectified by the inauguration of a cradle competition between these two classes. In this matter, the example of the inferior classes, the fertility of the feeble-minded, the mentally defective, the poverty-stricken classes, should not be held up for emulation.... On the contrary, the most urgent problem today is how to limit and discourage the over-fertility of the mentally and physically defective.margaret sanger
The third group [of society] are those irresponsible and reckless ones having little regard for the consequences of their acts, or whose religious scruples prevent their exercising control over their numbers. Many of this group are diseased, feeble-minded, and are of the pauper element dependent upon the normal and fit members of society for their support. There is no doubt in the minds of all thinking people that the procreation of this group should be stopped.margaret sanger
