If it is frightening to Dr. Carson that I want equality, then he is being irrational. If he views my desire to be equal as divisive and merely an aspect of "PC culture," that makes little sense. If he believes that wanting to be treated equally under the law is provoking some sort of war, making enemies and destroying this nation, then he is not thinking clearly.
The religious views of some may make our blood boil, but allowing these views in the free marketplace of ideas is the price we pay for a vibrant secular democracy that we all desire. If we yield to the temptation of censoring the views that offends us, we risk being censored by those who may find our views offensive.
