Part of my crusade is to establish firm understanding of what "chemtrail" entails...
Chemtrails are loosely defined by most CTists as Chemically altered contrails that spread out, and become clouds, or become whole cloud layers... with
"nefarious purposes"
so the belief in Chemtrails requires a belief in the nefarious plot of the people doing them...
that definition is BS... and goes to show the efforts of others to cull and cut the vast majority of true Chemtrails from the equation...
If we drop the nefarious requirement, then we can see that many weather manipulation methods ie: rain causing, and hurricaine moderation easily
qualify as chemtrails.
then we have the testing proposed, regarding solar mediation techniques, using sprayed metals/agents into the upper atmosphere... and although it is
claimed to be only in testing, I am sure that someone somewhere has had to deal with the downwind effects...
And here is the ONE valid source I have found for intentionally released biological warfare agents upon American cities...
US biological weapon tests upon american cities
I had a hell of a time finding that, so please bookmark, and copy the article... it may have missed the coverup culls...
from the article, here are the highlights.

"The human populations didn't know, the local governments didn't know, this was a secret army project that went on for 20 years," said author
Leonard Cole.
The U.S. government was preparing for germ warfare by secretly spraying biological agents on its own citizens. The tests were conducted in 239 cities,
including one of Oklahoma's most prominent communities.
"Among the hundreds and hundreds of tests that the army did, Stillwater, Oklahoma was targeted," said Cole, an expert on the Army's development of
biological weapons. In some cities reports indicate Americans actually died because of the testing.
Government records show florescent particles of zinc cadmium sulfide were released in Stillwater in 1962.
"Cadmium itself is known to be one of the most highly toxic materials in small amounts that a human can be exposed to," Cole said.
I challenge any skeptics or doubters to explain that one, before they deny anything...
because without addressing the absolute proof of biological weapons testing on Americans, then their denials will be as so much empty wind
