All this time the chemtrail people I know have been talking about weather control, I hadn't heard of mind control being part of it.
My take has been yeah I know cloud seeding and solar geoenhineering is real, ergo some amount of chemtrails are "real" in that they are deliberate particulate being sprayed and not just water. While the thing the chemtrail people claim that seems dubious is the scale and other nuances - claiming that all contrails are chemtrails. It's the scale that we don't know and that I assume it's pretty small because it seems expensive and pointless to do it constantly. But I don't know how I could ascertain the scale at which it's done either.
