You don't know that it's illegal to enter a classroom without permission? Even if you really, really think people need to give you time & attention & listen to you, this doesn't mean you have the right to make them via stalking & turning up at their work.
This is a thing you have now - 'Skeptics are not skeptical because they won't listen to me & admit that I am right.' Write loads of things about how wrong they all are. Hold conferences about it in their university campuses. Leave individuals alone when they ask you to.
