The cards, we’re assured, are “a concrete way to deal with an unsafe situation.” Though given the consequences of recent attempts at intervention – or what Bay Area Rapid Transit refers to as “allyship” – readers may wonder whether prompt and meaningful assistance may be less frequent than one might wish. Perhaps we can look forward to the issuing of “I am being stabbed” cards. And some “The man next to me is masturbating” cards. It does have the makings of an unhappy board game.

By issuing little cards, they’re creating “new social norms.” To supposedly address the problem of having created other “new social norms” in which punishing criminals is deemed unjust, racist, and terribly old-fashioned.

But hey, if you’re travelling to work on a BART train and some deranged creep starts masturbating against your leg, or pissing on the floor, or you find yourself standing next to yet another knife fight, or overdose, or commuter mugging – and no-one else does anything, or dares to do anything, except watch impotently and demoralised – because even noticing such things is racist – at least you’ll have a little card to clutch. Apparently that’s something.

In short, female customers who perceive incongruity, discomfort, and possibly danger should simply ignore those perceptions. Danger, it seems, is something one can now just pretend away.

You see, in the progressive pecking order, the fantasies of sexually dysmorphic men – and the preferences of male sex offenders – are of much greater importance than any “discomfort” felt by the women and girls on whom the former groups choose to impose themselves. Women and girls whose role, it seems, is merely to understand and tacitly affirm. To be reluctant accessories to some strange man’s psychodrama, while remaining free of judgement. Which is frowned upon.

Because the modern, not-at-all-insane response to repeated acts of indecency and sexual intimidation – by a predatory man in the women’s changing rooms – is to ask him not to keep waving his erection at women and children. On grounds that what he’s waving could somehow be a lady’s penis. Such is the sophistication of our times.

If, for instance, I were considering whether to amuse myself by flinging tomato juice over people and over their computers and whatever, while grinning with satisfaction, I’d expect a not insignificant likelihood of consequently being punched in the face. This expectation is important.

The risk of being punched, vigorously, is important. It inhibits quite a lot of recreational malice.

Habitual car theft is a “victimless” crime. Says Nora the socialist. Nora doesn’t think that a third conviction for car theft should result in incarceration. Because, and I quote, the victims “get new cars though.” “I write books and I know things,” says Nora, who lives in Quebec, where, in the last year, the rate of car theft has practically doubled.

Perhaps it would be ungentlemanly to wish on dear Nora some first-hand experience of the crimes she so merrily diminishes when inflicted on someone else, someone who isn’t her. Though it is, I think, tempting.
