When you say you have gained some insights about a domain, it sounds also like you might be a crank, for example if I gained some insights regarding topology and stochastic processes and was going to devote time to working on it, I would actually be a crank and end up sending my important mathematical proofs around to people who would be hard put to respond charitably to my ravings. Not saying that's you, but lots of otherwise sensible people gain insights into something outside their normal realm of expertise and then go on mad errands to save the world, generally very intelligent people, not realizing that these domains require more than just intelligence to gain an insight into them but also many years of study.
Finally when someone says they have a paradigm changing thing but cannot divulge it, some people may feel the person is either pretentious and does not realize they do not have paradigm changing thing, or that the person is unhinged (because talking about paradigm changing things before the paradigm has been changed will naturally sound unhinged to some people)
All of which says if you believe strongly you can change the paradigm you will have to do something to show it to people, and even the people you show it to (in my experience) will probably be too limited to see then possibilities in what you propose. The proof is in the pudding, and the weirder the pudding the more you will have to work to get people to eat it and realize how delicious it actually is.
Also when someone says their idea sparks fear in them because of the implications this is also a weird thing, because it implies what - a possible result of your idea is dystopia, mass extinction...? This contributes to the whole feeling like maybe you are overthinking the situation.
