It is just indicative of a general ignorance of science, which unfortunately is disturbingly pervasive in our society.
Like I said before, I'm not asking people to be able to define it as (3E8*60*60*24*365.24)m, only that they be familiar with the unit, that they know it to be a distance, and a very long one at that.
