This kind of simplified thinking causes so many issues. Like people avoiding fluoride toothpaste because fluoride bad. Or people not getting important vaccines because they contain minuscule amounts of something harmful. Or the alarm fatigue that cause people to just stop paying attention at all, like with "known to the State of California to cause cancer". We have to know how harmful something is to know whether to bother fixing it.
