As
heard by me a few moments ago on the local public radio station. Listen to what the "expert" says at the end of the interview.
It is perfectly natural to regard anything girls and women do as yucky, because even adult men do so. Well, this particular adult man does. And he quotes Michael Gurian as an unbiased source.
The point of this post is to pay attention. Pay attention to the muttered and whispered things which go for neutrality in these kinds of discussions.
