It is sensitive, but I think that it depends on where it comes from. If an equation is given as a copy of a page of a journal, then it should be protected, as a picture of a seriph in a cartoon should be.

Of course, I believe that there are few such cases compared to other species of pictures, and hence what we should care first is not them. Pictures from cartoons themselves are offensive even if they are not posted in order to harass someone, because the posters directly offend creators' right.
