This is irrelevant to what we're talking about. This is another standard conspiracy theorist tactic; pivoting and bringing up other events and circumstances. This is the height of intellectual bankruptcy. You're engaging in all sorts of fallacious reasoning in a desperate attempt to prove your preferred reality. I know you think you have it all figured out, but in your broken process all you've don't is come to the wrong conclusion.
Discussion
You absolutely lack any critical thinking skills whatsoever. These are all examples of previous malicious behavior by the US government. The list goes on. I can provide you further past events that are all in alignment with the government conducting tests on unwitting individuals. These are absolutely relevant in this discussion and context as one must discern the likelihood such actions as chemtrails might be viable. Your inability to comprehend this is truly astounding and demonstrates your ignorance.
Past examples of something partially similar to the chemtrail claims we're talking about are irrelevant to question of wherever there is currently a long term campaign of government planes spraying the population with "chemicals", and which the conspiracy theorists point to normal contrails as being proof of these chemtrails. And you really need to look in mirror before accusing others of not using critical thinking. Because your entire argument, and pivots, and appeals to past instances of malfeasance are nothing but one fallacious heap of nonsense. Nothing you have provided proves the assertion being made; that the government is currently engaging in a program to spray the population with chemicals, and that the proof is the existence of contrails. Prove your claim. All this other stuff is nonsense and irrelevant to the truth or fiction of the truth claim.
