Because of the convenient interpretation of Hinduism along racial lines instead of inherent individual qualities, it was vulnerable to being embraced by notorious racists groups such as the Nazis.  In India itself, racial application of the religious system certainly predates Nazism.

And, Hitler borrowed many of his ideas from outside of Germany include the Swastika, racial supremacy of so-called Nazis Aryans and even some forms of torture used in the Holocaust. And actually, the more the fund of knowledge will become penetrated, revealed and made available, the more it can be expected to be espoused, exploited, and claimed by racial superiority and bigotry.
