Darn it, I thought I'd solved this one before I went to bed last night.
Men: Take a moment to consider your ordinary behaviours and how they might sometimes inadvertently alarm or intimidate women. Adjust them. This may inconvenience you slightly.
Also, adopt an attitude of awareness of your surroundings and the behaviour of other people, at all times of day, so that you could at least act as a witness, perhaps call the police, or, in a sufficiently low threat scenario, intervene in a low-key way e.g. speak to a woman who's being bothered, about something inane, to give her a 'get out' and a witness, then, once she's got out, leave her alone yourself.
Plus, challenge your friends if they're ever sleazy, creepy or adopt a pack mentality towards women.
Small, everyday actions, attitudes and adjustments.
All you're giving up is your right to obliviousness.
No psychos, no fights, no heroics.
Yet those last cartoon capers seem to be all that the men on thread want to talk about.
So that my constructive, logical, relevant, evidence-based proposals were ignored, even dismissed - by men who 'know better' despite, by their own evidence, knowing near nothing of what we speak.
Gah.
