And you can't articulate a single argument to demonstrate understanding. A long list of mistaken websites adds up to exactly nothing.

Geoengineering Watch is ludicrous. The guy in charge clearly does not understand what he is looking at. Chemtrail Planet doesn't understand basic meteorology or cloud formation. If that is a measure of what you think is convincing, there is no reason to go down stupid rabbit holes. The end of it is that there is no evidence that anything is going on (barring small-scale cloud seeding). HAARP is a nothingburger. Patents and plans are programmatic dreams. The problem with all this is not so much that you don't have evidence to prove your contention (which you don't) but that you don't understand what would be needed to establish that proof.

As someone else has pointed out, Tennessee passed a law forbidding chemtrails. But the contrails continue unabated. And they will do the same wherever such a law is passed. The only way to stop contrails is to ban high-altitude flight altogether. And then what have you done? Nothing. I live in a region of considerable continuous cloud cover, and these moans and groans about contrails "blocking the sun" should be embarrassing. Those people have no idea what "blocking the sun" looks like. Or the fact that it doesn't stop normal life or agriculture.
