Well, not quite. But what he has to say about feminism seems applicable to similar social movements:
“So far as feminism seeks to adjust the legal position of woman to that of man, so far as it seeks to offer her legal and economic freedom to develop and act in accordance with her inclinations, desires, and economic circumstances–so far it is nothing more than a branch of the great liberal movement, which advocates peaceful and free evolution. When, going beyond this, it attacks the institutions of social life unde the impression that it will thus be able to remove the natural barriers, it is a spiritual child of socialism. For it is a characteristic of socialism to discover in social institutions the origin of unalterable facts of nature, and to endeavor, by reforming these institutions, to reform nature.”
