Conntrails disperse, chemtrails spread out, how to refute this?

One of the misundertandings going around is the claim that conn-trails disperse quickly whereas chem-trails spread out. I'm guessing that these different effects are due to different atmospheric conditions such as temperature, altitude, pressure and humidity.

Does anyone have a more precise explanation as to why some conn-trails take longer to disperse than others?

That's the central 'hook' which most believers are saying to me on twitter.Information is here somewhere,along with other FAQs - http://contrailscience.com/how-to-debunk-chemtrails/

David, this page in particular addresses the question pretty well: http://contrailscience.com/persisting-and-spreading-contrails/

In a nutshell, contrails have always been seen to be persistent under the right atmospheric conditions - when the plane is traveling through high-RH, low-temperature, "ice supersaturated" air. This was observed in the WWII era, has been studied since the 1950s, and is well-documented both in the scientific literature and in popular media.

How is this a misunderstanding? this is FACT

Notice unregistered doesn't answer the explanation in Belfrey's thread.
