Again, whose careers have been lost unfairly?
In Sweden there was a number of prominent men, mostly journalists targeted by #MeToo. The main problem was that the leading voice in the Swedish #MeToo had for years tried to frame a prominent Swedish journalist called Fredrik Virtanen, in what only can be called harassment. He was Sweden's highest paid journalist at the time. She had already reported him to the cops and had the case thrown out. This was in 2014. Then #MeToo came and she banged on the big drum and accused him. He was fired and completely frozen out of the jobs market. Screwed. That's just the most prominent. A cold case that had already been reported and dismissed should not be the grounds for firing anybody. Nor be taken seriously by anybody.
There came a lot of accusations of minor people. Industry by industry witch hunts were carried out. The methods were all the same. Various groups of women on Facebook would list suspects and then them down. Shrill feminists would rail in the media against these people and everybody knew who they were talking about without them naming names. And these could operate unopposed.
Sweden's most famous comedian, Soran Ismael's career was similarly destroyed. The accusations also turned out not to stick. He's now left comedy a studying to be a psychologist.
As far as I know only a single one of these men had anything tangible against them. Martin Timell. The rest was all bullshit.
So it had a huge impact on Sweden
I tried to look up those stories as best I could since had to translate articles. From what I can tell, Virtanen was accused by several women of misconduct, not just by Wallin. Her accusation was not prosecuted, but insufficient evidence to prosecute criminally does not mean it's a false accusation. Lack of evidence comes with the territory for these allegations, where often two people are alone in a room. Are victims supposed to shutup unless they have video evidence? It seems they are in Sweden, because Wallin is now being prosecuted for supposedly harassing him by simply accusing him. Is there evidence she she lied? If not, that's very odd to try to punish her. It looks like the playing field is uneven against accusers.
I am not as familiar with Sweden, but I can tell from the US where metoo began, that there is not some egregious onslaught against men going on. As Tom said, there could be a perception that there is even if false, and that is a risk of speaking out of course, but it doesn't make it wrong to speak out, any more than a wrongful conviction means we should abolish the justice system. Even that there are false accusations, it doesn't make metoo a harmful movement on balance. There is no comparison as I see it to any harm being done to the accused, compared to the harm done to the accusers for ages and still ongoing. It's like that saying, "Men are afraid that women will laugh at them. Women are afraid that men will kill them."
