What? Everyone uses children to advance a political agenda. Think about it. Education reformists, pro-life orginizations, homosexuals, the religious right, and my own highschool alumni association all use children to a greater or lesser extent to push their own agendas. Are they all terrorists?
I said the word "terrorist" is a stretch...these sick people are directly recruting children to protest their sick way of life so maybe they should be considered terrorists. Possibly I should have added a /sarc tag to the last sentence.
