flag burning vs global warming

According to a Pew Research poll of Americans, more people think that flag burning is more important than global warming. I would that is the result of ignorance of the facts of global warming. That's disheartening enough. The thought that Americans think that flag burning, which is very rare anyway, is more important than the life of large numbers of people, would be truly horrifying.
