Here is a response to the salon.com article--http://www.waldorfanswers.org/OnSalonArticle.html
I'm not totally enthused about this response. It is very long, it gets into a lot of complicated stuff and I doubt if many people will be willing to read it all the way through and figure out what is actually being said.
Unfortunately, however, it is very easy to take snippets of stuff that Steiner said and make him out to be a horribly bigoted nasty weirdo. He wasn't. I've been reading stuff by Steiner for (oh my!) forty years now. In all that reading, I've rarely run into remarks that are bigoted, even by today's stringent standards.
What I've noticed being done, is that the critics have a fairly small stable of outrageous quotes which are trotted out (sorry for the screwy metaphor) over and over and over again. The claim is made that these are a small selection of a huge number of biased remarks, giving the impression that every other word coming from Steiner was an example of blatant racism. Nope, the outrageous quotes are all there is, basically. Out of 350 large volumes, totaling over 80,000 pages, the total selection is pretty much what you all have probably already encountered.
Further, many of his remarks on the topic of race and ethnicity are arguing in favor of inter-marriage, and against nationalism (including German nationalism).
To give one example out of many, when the Protocols of the Elders of Zion
was first published and promoted as proof of a world-wide Jewish conspiracy, Steiner was one of the few folks around who immediately identified it as fraudulent and spoke out against this document as an inciter of anti-semitism.
