The short answer; No.
The long answer is also no, but with a bit more explaination. To make this as quick as possible, let’s have a look at what Steiner actually said about race. Firstly;
Therefore, in its fundamental nature, the anthroposophical movement… must cast aside the division into races. It must seek to unite people of all races and nations, and to bridge the divisions and differences between various groups of people…
That is why it is absolutely essential to understand that our anthroposophical movement is a spiritual one. It looks to the spirit and overcomes the effects of physical differences through the force of being a spiritual movement. Of course, any movement has its childhood illnesses, so to speak. Consequently, in the beginning of the theosophical movement the earth was divided into seven periods of time, one for each of the seven root races… However, we must get beyond the illnesses of childhood and understand clearly that the concept of race has ceased to have any meaning in our time.
And secondly;
Allow me…to greet you in the warmest way with that deep, inner feeling of unity that belongs to Anthroposophy, and in which all people on earth can unite without distinction of race, colour or any such thing.
Sure, there are people who have misenterpreted what Steiner said, and people who try to use Steiner’s work and the Anthroposohical movement to justify their own bigoted beliefs. This is a simple fact. But i hope you have seen from the two examples above (with many more examples like it) that Steiner’s work at its core specifically promotes unity among humans, moving above earthly differences like race.
These types of people can be found in essentially every movement, but from my own personal experience in the Anthroposophical movement, those who try to use Anthroposophy to justify racism are not welcome.
What we can say in a post we’re trying to keep as short as possible is simply this; Bigots of any kind are not representative of the Anthroposophical movement in any form. Bigots will find out very quickly that they are also, on a practical level, not welcome either.
