No, critical thinking requires you know something about the subject you discuss before making extraordinary claims.

Using the DC/KC-10 chemtrail movie as an example. The original was a chemtrail spoof made by a KC-10 pilot. The KC/DC-10 has distinctive flap actuator fairings under the wings (search airliners.net for many, many photos showing these). But the person who "believed" this chemtrail hoax bought the "nozzle" story without knowing what those objects under the wings really are.

He also hasn't read about/studied/bothered to learn about contrails, which have been around since we started flying way up there. He simply believes in chemtrails and cannot be bothered with contrary information.

The OP video here demonstrates a complete lack of knowledge of how ATC works, more laziness/gullibility by the OP. He calls all these planes "KC-135s" when in actuality there is no way to determine the actual aircraft type. Airbus has several 4 engine models, and Boeing has it's 747 (one of which was shown in the video, again implied as a KC135).

Call me a chemtrail skeptic...prove to me that the materials found in the soil and water are (a) not from natural sources, and (b) really from aircraft and not some groundbased source.
