Unfortunately it's a reflection of society in general. And society is very, very uncomfortable with the idea that so many men are sexual abusers or predators and that many are not very clever about hiding that fact (or, worse, like to flaunt it in plain sight in the safe assumption that no one will do one bloody thing about it).
So what gives instead? Must be the women who are lying. And worse, children. Hence the 'no one will believe you' defence. No one wants to believe their jolly, somewhat eccentric, avuncular colleage - who waddles, quacks, looks and swims like a duck just as Savile did - would sexually harrass a less-established colleague, so she is the one branded a morally reprehensible liar. (This, BTW, is my own personal experience).
Look at SM and you realise you've not encountered this attitude in isolation. The horrifying thing about #MeToo wasn't the volume of responses - that sadly didn't come as any great shock - but the vitriolic tone of the pushback against them. Women should shut up. Women are jumping on the bandwagon. Why don't women report it at the time? Women are lying. People simply do not want to hear it, and when they're being told loud and clear - even when unassailable evidence exists cf. Mel Gibson and Oksana Grigorieva - they put their fingers in their ears and go 'la, la, la'.
Same applies to the attitude to the sordid Andrew debacle. 'He hasn't been convicted of any crime!' (Course he hasn't). Or, in the discussion columns: 'Not this again! Boring! Make it stop, make it go away!' And the victims? 'She just wants money'.
I have to take a step back from the www at these times. Makes me incandescent with anger, but I want to cry at the same time.
