I have sometimes wondered whether the whole chemtrail thing was originally an experiment to see how readily people would accept a new
'conspiracy'.
It's actually quite clever because most people - unless they have an big interest in the weather, in landscape photography, or in plane spotting -
don't look up at the skies much, and rarely notice what aircraft fly over their homes or what clouds there are in the sky . So it's easy to
convince them that lingering contrails - and even things like irridescent clouds - are 'new' phenomena. And if you suddenly start looking up at the
sky then "Wow! They're right"! I hadn't noticed that before...."
And once you've been caught in the conspiracy then it soon becomes obvious that all those folk who have been looking at the skies for decades, and
know that it's all completely harmless and natural etc and try to explain it to you, are clearly just disinformation agents.
After all, why else would someone be so determined to convince you that chemtrails don't exist?
