Totally agree with your point about due process at the criminal and university-disciplinary levels, but the current public outing of a-holes is neither and falls well within the victim's first amendment rights. Should they press charges due process certainly applies.
Now will some folks make false claims, yes. Does that mean we stifle or limit people from making these claims, no. We have a system for addressing these through slander and libel laws.
Also, related to the current set of allegations, the media has appeared to act with professionalism when determining when a story is sufficiently vetted, whether to reveal names, etc... I can't think of a well known false allegation since the onset of #metoo -- that'll eventually change, but like so many other things in life, our freedoms cannot be limited just because a few folks use them improperly.
And I totally agree that due to the wave of folks coming forward, everyone ought to think more carefully about their behavior, and that, as you said, is a big positive.
I think due process in spirit matters to since there are major financial and social consequences to the current situation. One could sue for slander or libel but then effectively creates a flipping of due process anyway. People are being convicted in the court of public opinion. The allegation is enough to taint and damage. It’s not an easy thing to defend against, which is why it’s a powerful weapon.
