I agree with wcoltd, it probably has a lot to do with the way you're communicating your symptoms. Lots of people present with misguided self-diagnoses these days, and a professional's experience of this may lead them to assumptions. Based on what you've said here I think you should at least be assessed by a mental health professional.
Schizophrenia is a mental disorder characterised by a range of "positive" and "negative" symptoms. "Positive" symptoms basically cover Psychosis (hallucinations and delusions), however there are a number of other symptoms presents, such as a break down in thought processes, disorganised speech, and poor emotional responsiveness. It is a complex disorder and generally requires some ongoing monitoring of symptoms before a diagnosis could be made. The presence of psychosis does not necessarily indicate schizophrenia, and there are a range of causes. Drug-induced psychosis is relatively commonplace, and can occur as a result of both recreational and prescription drug use. Even "soft" drugs such as cannabis can trigger a psychosis in susceptible people or heavy users, so this is worth bearing in mind. Psychosis can also occur under stress in the context of some personality disorders, such as schizotypal or schizoid, or even emotionally unstable (in the US, borderline) personality disorders.
I didn't see the thread where you'd been talking about Nazis that others have mentioned, though fixed ideas of this type could indicate a Psychosis. This isn't clear cut, though, since these types of symptoms occur across a scale. For example, somebody with very high anxiety levels might experience so-called "sensitive ideas of reference" - generally a more transient experience, which can involve derealisation/depersonalisation, rather than the more fixed and irrational beliefs typical of delusions, which typically occur with very limited or absent insight. That said, holding beliefs that others do not find easily relatable doesn't necessarily indicate a problem - some of us are just eccentric, or are subject to different cultural influences.
I would suggest discussing it with a health professional again, with focus more on the individual symptoms and the contexts in which they occur, rather than upon diagnosis.
