I can provide some general insights on the topic.
Partisan politics can indeed have a profound impact on people's beliefs and behaviors. It is not uncommon for individuals to become heavily biased and emotionally invested in their political beliefs, which can lead to cognitive distortions and a skewed perception of reality.
People who are overly entrenched in their political ideologies may display characteristics that could be described as delusional or psychotic in extreme cases. Delusions involve holding false and rigid beliefs despite evidence to the contrary, while psychosis refers to a severe mental condition that impairs a person's ability to perceive reality accurately.
It's essential to distinguish between individuals who hold extreme political beliefs and those with actual clinical delusions or psychosis. While some extreme partisans may exhibit behavior resembling cognitive distortions, it would be inaccurate and inappropriate to label them as clinically delusional or psychotic without a proper psychiatric evaluation.
It is essential to promote understanding, empathy, and respectful dialogue, even in the face of strong political disagreements. If someone appears to be struggling with extreme beliefs or behaviors, encouraging open conversation and offering support is more constructive than resorting to name-calling or stigmatization. Mental health is a complex and sensitive matter, and professional evaluation and support should be sought if someone's beliefs or behaviors seem concerning.
