This is ridiculous. The #metoo movement is not focused on "witch hunting", there are many different people associated with this "movement" and there is no real guiding person or organization that is focused on it. Individuals may be trying to take advantage of it, but don't throw everything out because of a couple rotten actors (that you perceive).
Except the figure head of #metoo was found to be as guilty as the rest of them [1]. Every actor or celebrity screaming #metoo is a hypocrite who was happy for the status quo to be a culture of assault and degradation, until it became convenient for them to say otherwise.
Then they passed it on the culture-at-large saying everyone has this problem, when it is vastly concentrated in Hollywood, which has lead to social breakdown [2].
There is no doubt that humans are shitty. Was that ever in question? The #metoo movement has brought forward, and into public discourse, a problem. Had this not been brought forward even Argento's indiscretions wouldn't be known. The things highlighted by the #metoo movement are impactful and important to the advancement of our society and civilization. These actions should not be considered "OKAY" and most people who say the #metoo movement is filled with witch hunting and should be stopped are effectively discounting any of its gains. Nothing is perfect, but we can all strive to be better—and maybe with #metoo visible in the world we can avoid the problems of the past in our future.
I believe the other two persons arguing with you here are simply saying that #metoo has a noble agenda but was quickly hijacked to push other people's agendas. Which is sadly a pretty classic scenario IMO.
Most are against due process? As in most supporters of #metoo or as in the most visible and loudest supporters that you have focused on? Do you have any kind of real statistics about the supporters of #metoo or are you making an inference from what makes the headlines from your chosen media?
