True if you think everything contrary is simply a matter of free thought. At some point, though, is there not a dividing line between free thought and delusional foolishness? It seems as if these days one of our problems is that we are obligated to respect every stupid idea that comes around as just another way of looking at things. There is a consequence for abuse of free thought, if it involves physical realities that are immediate. You fall to your death, die of disease, kill your kids, get run over, have a heart attack, get bitten by the snake, mauled by the bear, and so forth. But somehow when the consequences are not immediate, idiocy becomes controversy, smoke bombs threaten fire, and we end up endangering the very earth because we must respect even the most flagrant delusions.
I do blame religion for much of this. To varying degrees, adherents of various religions are taught that it is not only permissible, but necessary, to deny the obvious. It's hard to keep that genie in the bottle.
