• If facts or scientific research is not available then it is simply a normal discussion, rumour or suggestion. This is still a difference and not per-se a conspiracy.
• Facts and conspiracy theory have nothing to with each one another, you can also spread conspiracy theories with, so-called facts that might be contradicted or debunked later based on new research evidence or on misinformation. Combining everything usually goes hand in hand, someone thinks he knows xyz and then start to spread moral panic.
• You mix conspiracy people, as generalization term with people who deliberately spread misinformation.

Now drop the topic, this thread here is not about conspiracy people and I am not here to explain you what it is, check Wikipedia.
