I would like to think that speaking the truth is the solution but it only works with those who actually have the capacity to think and reason. In contrast, big money has the luxury of buying and promoting the media view points that they want us to believe. Most people take the easy route that doesn’t involve the work of thinking. Discerning truth is work - believing bullshit is the easy route. It has been my experience that both those on the left, and right, fall for the “chemtrail” crap.
As climate change kills folks off, some will survive by learning.
When people begin to starve or become homeless they will be forced to confront survival rather than conspiracy nonsense.
