I was involved in children's rights when I was 18-23. Big issue
  for me. Still kinda is. I made a mailing list in 1990 (first
  child@hampshire then Y-RIGHTS@SJUVM) to bring people together on
  the young Internet and "18 year old me" wasn't surprised when it
  gained thousands and thousands of members, including
  International Organizations.

  This one I came across in my files the other day. I would have
  been 20 years old at this point. Other members of the UN were
  already members, Amnesty International, as well as various
  Universities and government Think Tanks... as well as kids and
  teens themselves.
  They talked about every issue under the sun and it spawned many
  collaborative efforts that still exist to this day on
  Unparenting and Unschooling issues, national children's rights
  organizatons in different countries (right to vote, right to
  drive, right to drink, right to education),

  It's still an issue I'm passionate about. In general it falls
  under the category of "Ageism" in general; even then it wasn't
  so much "about the children" but it was about age discrimination
  in general, power structures and the like.

  The problem is: Once people are 18, they usually stop caring. Or
  they care only from an "adult perspective" only and forgot what
  it was like.

  Oh well. It's probably why I'm so 'bleh" about politics being a
  vehicle for change. Unless you live in a small country, it's not
  an effective means for change generally, unless the movement you
  are a part of is overwhelmingly powerful.
