True or false doesn't matter, I can lie or tell the truth freely on all those topics:

"Dinosaurs don't exist. Never have. The world was made Last Tuesday, with everything in motion including historical records, pre-half-lived elements, and false memories."

Done. I can go into a public square anywhere in North America, even in Canuckistan, and declare that proudly and loudly to the forum. I will not be put into prison for two years for such an action.

"The TSA is security theater. They exist to make stupid cowards more comfortable about flying, not to actually catch any threats."

Bam, still not in jail for two years.

"Due to quantum uncertainty, the atomic model of the atom is misleading at best, a properly accurate model would look very different indeed, if it were even possible to create."

Still not in jail.

"Fluoride is added to many water supplies supposedly for teeth health, but when you look at the insanity rate of people in the middle/ren ages, in these massive asylums compared to today with out 10000x larger population and seemingly the same pure number of ailed, and take into account fluoride's effect as a mood stabilizing drug, there's merit in the theory that it is impacting the psychological zeitgeist, and if so, one must ask if this was an intentional effect."

No jail.
