No one here is actually asking for your sources, so far as I can see. The people who are taking umbrage at your comment are most likely (like me) those who do not see your explanation as cogent but instead an assertion that doesn't even fully explain what is asserting. You're promoting a conspiracy theory--a shadowy "They" who are conspiring to do something--without explaining what the conspiracy actually is. What are the myths being enforced? Why are "They" doing this? Who even is "They"?

> But how does one gather a reputation such that whatever I say will be read mindfully and not just dismissed right out when I start to make reasoning leaps all around? the most direct way is to simply repeat what other people with a reputation have said; to preach to the choir.

In my experience on HN, that reputation is gathered mostly by being seen to speak authoritatively on topics. The highest upvote comments I have gathered are generally when I can put together thorough, concise explanations quickly. It doesn't have to agree with the current zeitgeist, but you do generally want to provide stronger argumentation for your viewpoints in that situation.
