That's ridiculous. So if you run for any position of power, anyone can come out with a claim, an unsubstantiated claim and then you're disqualified automatically? That's a dangerous and undemocratic precedent and bound to be abused.
It is actually IS being used and abused. One cannot look at the timing and nature of the accusations (whether true or not) and not see this as anything but the #metoo movement being polically weaponized.
