Feminism (?) (!)

       I have heard the word (feminist) or some derivation or pejorative (femi-nazi) banded about in the media or my social community for years, but really couldn't put my finger on it.  Well, as my students are working on research projects around the end of the Victorian Era (and its influences in the United States) and the heart of the Progressive Era, I came across the term in our textbook.  It dawned on my that the first wave of feminist came about with Margaret Sanger, Alice Paul, and the ladies of this era.  In my Master's level Historiography and (oddly) a Foreign Policy course a few years back, the topic turned to the different waves of feminism in American history, and their use as a lens to study the era and aspects of influence. 
      Second Wave feminism comes about during the turbulent times of change in the 1960s and after.  The push was to unite women the world over under a common agenda, and in rebellion to the 1950s conformity.  Ok, fast forward.  Third Wave feminism is, arguably of course, what we are in right now.  Some wonder if we are not entering a fourth, but I don't understand it well enough to make that call, I can only report what I hear. 
      Now, to cross streams of thought.  I am a huge fan of the singer Pink.  I prefer strong, edgy girl singers.  Oddly, I also adore Taylor Swift (its my inner Tween heart, looking for simple love).  But, when I saw her latest video this past week, the video for "Try".  Her words are always powerful, and speak to me of a batter heart.  But, when I saw the beauty of her body (well toned and sculptured), the dance she and her partner do in the video, the simplicity of the background, and then compare that to the violence they perpetrate on each others bodies.  It immediately took me back to Eminem's "Love the Way You Lie".  Pink (and Eminem) have both spoken to abuse in relationships, of hurting (physically) their partners.  Rihanna has been openly in an abusive relationship.  When Eminem raps about abuse, it is a man writing of a masculine anger in a sense that many will recognize, and fits a traditional mold.  When Pink speaks of fighting with her husband or a lover, you get the sense of an empowered woman who is strong enough to stand up for herself.  But, this video made me wonder:  Is this fourth wave feminism?  Or is this third-wave continued, played out?  When the first wave women are fighting for a declaration of marital rape, control of their own sexuality, and a voice, now what is the goal of feminism?  Pink, Katy Perry, Madonna, Lady Gaga, Rihanna, etc, seem to have taken up the gauntlet for female sexuality, but are demanding more.  It's complicated.  They want to be left alone.  They don't want to be a voice for feminism and equality in the traditional sense.  They want to be judged on their own merits.  They are open with their failures and back down to no man.  So, are they 3rd or 4th?  I don't know. . . . If it helps, compare first wavers in Iron Jawed Angels, second wavers with  Janis Joplin in concert in 1970, and then Pink, as our latest (?) wave.  I know, I just presumed that she is third wave. . .
