Hi, back again.

His attempts to reveal helicopters cant fly under gravity had to be silenced.

He's probably thinking exactly that.  "They couldn't handle my logic and the obvious truth of my knowledge, and so like cowards they silenced me!"

To be fair, though, I'm really getting worried about how many raving crazies there are in the world.  How can the internet exist, and schools and books, and people are still this fucking ignorant of even basic physics?

I'd say the internet is the cause of the ignorance. There will ALWAYS be a "source" to back up whatever opinion someone has about something. There will ALWAYS be a community, no matter how small, who believes the same thing or something similar. Facts simply don't matter anymore. We live in a "post-fact society."
