Margaret, you write:
"When you (a 60-year-old male Anthroposophist who seems to make a career of monitoring the Internet for criticism of Steiner schools so that you can yell "hate group!" or more recently "hate-type group!") ..."
I'm not 60, but I have been following the group you refer to for some 10 years, since I discovered it and started participating on the mailing of the secretary and driving force of the group, to find out what it was about and to the best of my ability and understanding try to address the issues discussed on the list.
In general, some of the discontent that comes to expression at the site of PLANS and the two mailing lists related to it stands out as valid and understandable and can be seen as partly rooted in a too rapid growth of the Waldorf movement in the U.S., resulting in partly immature schools and (like at most schools) at times not fully competent teachers and administrators.
Another part is understandable as an expression of a clash between a purely rationalist view of the purpose of education and an effort in Waldorf education to do a more balanced justice to not only the intellectual, but also the emotional, social and action oriented needs of growing children, and integrate also earlier perspectives and stages of the cultural evolution of mankind than the present in the Waldorf curriculum, in building an understanding of the pupils for their background and place in the world, not primarily as members of any specific nation or race, but as members of humanity and world citizens.
The third main part of the argumentation uses the first two parts as a basis and implied support for demonizing defamation, smearing of and witch hunting against Waldorf education, anthroposophy, the anthroposophical movement and Rudolf Steiner as the main originator of both anthroposophy and Waldorf education, as part of the mainly secular humanist rhetoric of the originator of the site of PLANS.
Except for the myths mentioned here, the main tools used in this part of the argumentation are the cultivation respectively support by the secretary, president and vice president of PLANS of allegations on the WC-list, then republished as "archives" at the site of PLANS, that Rudolf Steiner was schizophrenic, megalomaniac and a drug addict, that he probably practiced sex magic, and that elements in Waldorf education extensively are used as ritual magic, like eurythmy, or used to make "magical talismans" (wet-on-wet water-color paintings), and with the secretary of PLANS regularly comparing Steiner to Hitler.
It is the addition of the third type of argumentation, described on 10+ points here using the arguments of the first and second type as basis for it, that puts the group in the hate-type category.
