Good point Mick. Well, the short answer is... everybody does it. You made a forums before you had all the facts, and the facts accumulated. You did not research every possibility before having a discussion, because nobody can. That is what discussion is for. The long answer is... you would need to make a new thread for every single topic and moderate the threads heavily or have some type of automated system. This would take much more time and effort. To give the situation a happy outlook, I would say that I have at least done some research before discussion, and that I have made you ask a few questions yourself. I rarely bring up topics that have been answered but I understand how it is frustrating to get the same questions over and over from people. I am an individual here remember... So let's not try to think about this problem too much in our discussions unless it becomes a continuing issue.
One can never have all the facts about a broad topic. So if people waited, then nothing would ever get done.
However:
I'm not trying to disprove chemtrails.
Sorry for shouting, but it's a key point you seem to be missing. I'm debunking. That means I look at the evidence, and I see what is bunk, and I explain why that particular bit it is bunk. My overall goal is to explain as best I can all the evidence presented in favor of chemtrails. It is not to present evidence proving they don't exist - simply to remove the bunk presented as evidence that they DO exist.
So my question is not about how I can prove they don't exist. It's about how I can more efficiently communicate things like the explanation for circular contrails, or Aluminum in soil, or the persistence of contrails.
