Examples of reasonable beliefs held by the public:

"Won't somebody think of the children" is constantly used sarcastically in order to dismiss the concerns of people who want to ban something they claim is harmful to children. This is often a completely justified rejoinder - many regulatory policies that thoughtless people argue for in the name of children's safety are counterproductive, disproportional, or otherwise harmful.
