I was teaching a “Continuing Education” class and one of the guys started talking about ‘ChemTrails’?

The ‘Chemtrail Conspiracy Theory’ posits that some trails left by aircraft are chemical or biological agents deliberately sprayed at high altitudes for purposes undisclosed to the general public in clandestine programs directed by various government officials.

I’m not saying that he does not have a valid argument or that he’s crazy… I’m just saying that maybe somethings should be left alone and NOT brought up during a class.
