What term would apply to someone who makes conclusions based on exaggerated fears of an opposing ideology?

The term that accurately describes someone who draws conclusions based on exaggerated fears of an opposing ideology is tabloid thinking. This term reflects a tendency to simplify complex issues and present them in an sensationalized manner, often leading to exaggerated fears or misconceptions about opposing viewpoints. It involves focusing on sensational aspects rather than a nuanced understanding of the situation, sometimes leading to emotional responses that are not grounded in evidence or rationality.

In contrast, causal oversimplification refers to attributing complex phenomena to a single cause, which does not specifically capture the element of fear or ideology. Academic detachment implies a dispassionate and objective stance toward examining arguments and evidence, which runs counter to the idea of being driven by exaggerated fears. Rationalization is the process of justifying actions or beliefs to make them seem acceptable, but it does not specifically refer to the exaggerated fears linked to opposing ideologies. Therefore, tabloid thinking is the most fitting descriptor for the behavior outlined in the question.
