So let's say there are chem trails, the country is being sprayed. 50 years from now it comes out in the mainstream news that the government sprayed us for some excuse or the other. What's going to happen? Is the public going to apologize to the kooks who talked about chem trails? Are they even going to admit the kooks were correct? No. Few will even learn about the admission and those that do will just shrug it off.
Just imagine if undeniable proof surfaced that the CIA killed JFK tomorrow. It would be a story in the news for one day. People would shrug it off, never accepting the kooks were right, and keep on trusting government and calling those who don't kooks. It would change nothing. Normal people don't concern themselves with it. It's all conditioning and emotion. They'll say it happened a long time ago, those bad men are dead, and go on sure in their beliefs. The end.
Those who see current issues will still be kooks.
