It occurred to me today that for a certain segment of the population, chemtrails are an evil, deep state conspiracy, except when they’re part of an air show.
@jerry Weirdly, I think you may have hit on something. It's likely the ones who are concerned about "chemtrails" are (amongst) the ones who are most excited about the air show smoke trails. One is totally innocuous, the other probably genuinely toxic (though probably rather low, unless you get hit directly by it).
