"Those who rail against eugenics in any form engage in a technique where they conflate an easily defended position with a more difficult to defend position (AKA the Motte and Bailey strategy). The easily defended position is that we should not murder or forcibly sterilize people on the basis of their genetics or disability. This position is conflated with several more difficult-to-defend positions. These more difficult-to-defend positions include that we should not study the genetics of desirable or undesirable characteristics, that we should not label any characteristics as desirable or undesirable and that we should not consider how any policy could change the genetic propensities of future generations."
