Just asking but some of the people here seem very hostile to people that consider chemtrailing may be happening.
Can we blame people for thinking it is possible when even mainstream newspapers have reported on the existence of black-op projects?

Hostile? How so? People see to be very open to considering your questions, and offering you explanations for the things you have seen.
But, why are these germ war tests in any way linked to what you call "chemtrails"? Do they look similar?
And who has ever denied the existence of black-op projects?
