The problem is that parental figures previously based such general information on gut feelings, personal anecdotes and old wives tales. A lot of what parents say can be correct, but when there is a lack of information to fill the gaps to a childs understandable inquisitiveness it's filled with ignorance or scorn by the parents that are going through the motions who have no answer. It's an interesting dynamic with the resources available for information to the general public that it will be the children that can quash misconceptions perpetuated by parents. We all, including future generations, will become better parents for it.
