Politically, the right wing obviously has a vested interest in de-emphasizing a theory that unsettles its religious constituents. However, the specter of Social Darwinism is just as disturbing to progressives.
Except that Social Darwinism is offensive BS that pretends a relation with science. Unless you are in a discussion with someone with an anti-science bent, there is no reason to let go of evolutionary theory just to dismiss Social Darwinism.
On the other hand, the religious right largely forgoes any reconciliation of their views with science.
