No, being obsessed with Che Guevara or any historical figure does not necessarily mean that someone is autistic. Having an intense interest or fascination with a particular person, event, or subject is not uncommon for people, regardless of neurotypical or neurodivergent traits.
Autism is a neurodevelopmental condition characterized by differences in social communication, repetitive behaviors, and restricted interests. While some autistic individuals may develop intense interests in specific topics, this does not mean that everyone who has a passionate interest in a historical figure like Che Guevara is autistic.
Passionate interests can be seen in people of all neurotypes and are often driven by personal experiences, cultural influences, or intellectual curiosity. It's essential not to make assumptions about someone's neurotype or diagnosis based solely on their interests or hobbies.
If you or someone you know is genuinely concerned about autism or any other neurodevelopmental condition, it's best to consult with a qualified healthcare professional for a proper evaluation and diagnosis.
