You're doing exactly what the newspaper did. Going for the click bait.
There's not enough detail to judge if this is ridiculous and trivial and wouldn't happen if a woman had complained.
We know nothing about the man who complained and whether he was vulnerable in some way or about the other woman that was attacked.
We don't know what the seriousness of the affray was or GBH and in what context it happened.
Let's put this scenario forward. Disabled and mentally ill man out for a walk with his carer. Two women slap his arse ,maybe make some lewd comments. His carer intervenes and gets beaten up.
You still think it's ok and should have never gone to court?
It's also possible he was a 6ft ,able , rugby player and the women thought it would be a laugh or did it as a dare. Another women still got hurt,by them. I'd find it unlikely though , considering the risk and power balance going after such a man.
