It is a well known anecdotal fact that progressive/liberalism is a serious mental disorder. Such statements are at their core no different from those made by leftists who claim conservatism is a mental disorder. Further, they fail to make a distinction between three kinds of people:
- Those who out of apathy simply don't see the effects of leftist policies.
- Those who, in order to avoid contradiction with their views, have blinded themselves to the consequences of leftist policies even when those consequences are staring them in the face.
- Those who are well aware that the actual effects of leftist policies have no relation to their stated aims, but whose actual aims correlate to the effects of those policies.
While those in the second group could be regarded as suffering from a delusion disorder, and one could argue that the members of the third group are often sociopaths, I don't think leftism may fairly be described as
a mental disorder, especially given that the second and third groups are so different.
