Deciding that something is the "truth" simply because it happens to be what you "think" is a dangerous thing. Religious authorities used to say that the earth was both flat and the center of the universe. People who didn't "think" the same were burned at the stake. Those in charge "thought" it was so, therefore it was deemed to be "infallible truth". It was actually this pope who just died, John Paul II, who released a papal bull in the 1990's saying that the previous doctrine was wrong. Until the 90's it was still part of their church "law" that the earth was undeniably flat and the center of the universe.
Do some research. You can read quite a few postings on TBN of people who got poison oak or ivy smoke on their skin and were hospitalized. Some got lung infections so bad they were on steroids and other medications to prevent respiratory failure. Look up articles on web sites of universities and hospitals and read how serious the stuff is.
The world is full of terrorist who are so extreme because they think that their own "thinking system" is so brilliant that whatever they "think" must be ultimately true.
Still, however, science is about not taking other people's word as true. Science is about coming up with a hypothesis (something you "think" is "true") and rigorously testing it to see whether it really is true or not. So, here is what I propose. If you are really confident that whatever you "think" is equal to "truth", will you be willing to go set afire a large patch of poison oak, walk all around in the smoke, let it get all over your skin and in your eyes, breathe in as much as you can, and then give to us a couple of days later a full report of the results?
If you are so confident that whatever you "think" is equal to "truth", then let's see if you have the courage to try this little test!
