Asimov's actions, and the tolerance-up-to-celebration of it, absolutely drove women out of field and out of fandom, and made it easier for others in the field, writers, editors and fans, to follow his lead for decades. Asimov pinching asses was not about his work. It kept women and their work out.

It was hardly a secret, even back then. He wrote a book called The Sensuous, Dirty Old Man in celebration of his behaviour under the tissue-thin pseudonym Dr 'A'. The authorship was quickly revealed and the book reissued under Isaac Asimov.
