The conservative mind, in some very visible cases, has become diseased. The movement has been seized by a kind of discrediting madness, in which conspiracy delusions figure prominently. Institutions and individuals that once served an important ideological role, providing a balance to media bias, are discrediting themselves in crucial ways. With the blessings of a president, they have abandoned the normal constraints of reason and compassion. They have allowed political polarization to reach their hearts, and harden them. They have allowed polarization to dominate their minds, and empty them.
Conspiracy theories often involve a kind of dehumanization. Human tragedy is made secondary — something to be exploited rather than mourned. The narrative of conspiracy takes precedence over the meaning of a life and the suffering of a family. A human being is made into an ideological prop and used on someone else’s stage. As the Rich family has attested, the pain inflicted is quite real.
A conspiratorial approach to politics is fully consistent with other forms of dehumanization — of migrants, refugees and “the other” more generally. Men and women are reduced to types and presented as threats. They also become props in an ideological drama. They are presented as representatives of a plot involving invasion and infiltration, rather than being viewed as individuals seeking opportunity or fleeing oppression and violence. This also involves callousness, cruelty and conspiracy thinking.
