Actually, they weren’t.
You are, of course, correct.
Just because assaults went unreported, or weren't taken seriously doesn't mean they occurred less frequently.
And just because a woman is unattractive, it doesn't mean she wasn't harrassed.
Though I'm disinclined to believe Ms McCaskill, the problem of harrassment still exists, and if conservatives don't take it seriously, we will continue to lose the moral ground we ceded when we decided it was just peachy keen to nominate a reprobate to run for President, and to mock any conservative who dared to say it was wrong to do so.
