So you're suggesting we let people be misinformed? Where do you draw the line? Do we let our teachers teach the earth is both flat and round and "let the students decide"? The earth is the center of the universe and just a part of the milky way? The holocaust happened and didn't happen?
You can't possibly expect people to make rational decisions about science they don't understand. And letting people straight up LIE and expect the common man to spend hours researching a topic they probably don't even understand to figure out they're being lied to is RIDICULOUS. There's a reason why we have ethics in journalism...
