There has, I gather, been a lot of kerfluffle on LJ about default icons showing images of nursing, and the ban thereupon.
A friend of mine wrote up this short essay on her view of the matter
. If this kerfluffle is something that's at all important to you, I'd very much suggest that you read it.
The short form, though, is this: This is about the fact that U.S. laws on this sort of thing are vague, and that LiveJournal has a quite reasonable desire to avoid finding themselves in a precedent-setting lawsuit, regardless of whether they have a chance of winning that suit. My addition to that is: Regardless of whether you agree with the decision, if your protest has fewer teeth than "There's a credible threat that you could be sued over this," it's irrelevant and merely serves to increase the drama-fest.
