When feminism is working towards equality, towards human rights
   with an emphasis on feminist issues, it's working well. But when
   it's used as a line-to-divide and keep the divisions, it's
   ceases to be empowerment and becomes war. At present, the new
   outcropping of so-called "Men's Rights" might partially be a
   result of empowerment-gone-too-far, helping create an
   environment in which the aggressive and misogynistic "men's
   rights" has felt free to also go to war. The prior incarnation
   of feminism was a little more towards human rights with an
   emphasis on feminist issues but it's not just feminism that
   there has been a shift in society. It seems to have started
   somewhere in the late 1990s: an overall polarization. Less
   "We're all one humanity - let's be diplomatic and work on our
   issues together", and more "Us good, they bad", so it's not
   feminisms fault for changing. The change has been global and
   seen in many arenas.
