That comment in her diary that you're thinking of (I do not like the Jewish voice, etc.) is very sad, but she was really very young and it was before she really knew Leonard. They went on to have a very close, loving partnership, they of course deeply opposed Hitler and were involved in socialist or leftish politics (Virginia in her idiosyncratic way as befits a genius) and the attempts of some people, like the right-wing magazine Commentary and some feminist scholars in the 70s/80s to say it was a fake marriage because of that comment in the diary (further 'evidenced' by her being bisexual and them having an open marriage) simply show their complete lack of acquaintance with the actual materials of her life beyond a few features that stand out for use in their preconstructed argument.
