I think two things can be bad at the same time. I do think Retrospect is more problematic than Blood Fever because the implication in Retrospect is, "don't take women at their word". Vorik's assault on B'Elanna in Blood Fever is obviously wrong, even if it is not adequately addressed in the episode. OTOH the story in Retrospect makes it seem like almost a reasonable position to assume that a sexual assault allegation is false until proven otherwise. That's a problem.
It is very difficult for a woman to come forward with an assault accusation; and when they do those accusations are dismissed far too often. That leaves women with all of the consequences of coming forward, but without any justice, making it even less likely that future assaults will be reported. To put an end to sexual assaults, it's necessary to believe women.
