Conservatism is about slowing change. Change causes fear in those who are not adequately prepared to meet it. This is a symptom of someone who is mentally unhealthy. The level of fear is proportionate to the overall level of mental health.

All that to say: I think those with disorders are more likely to be conservative, but to a certain level conservatism is healthy.

MAGA on the other hand? That deserves to be seen as a disorder, imo.
