Ouch. I've seen quite a few family breakup analogies, but this is the first time I saw Scotland be the child instead of the spouse.
If we're going analogise a country to a person, actually I'd say it's pretty natural to seek out unions even though they involve giving up some independence. That's why people get married. That's why the EU keeps growing. Even the most perfect couples don't always agree all the time, but they find ways to figure it out because it's better together than apart. Divorces are universally considered a tragedy in our culture exactly because we recognise that unions bring strength: when one partner stumbles, the other is there to help.
Salmond's behaviour with Scotland has been like going to a wife in a working marriage where decisions are taken together and telling her constantly, repeatedly, that she's too good for the man she's with. That her husband treats her unfairly. That she's oppressed by him. That everything wrong in her life is her husbands fault. She didn't get the promotion she wanted? Husband's fault. She doesn't get enough attention? Husband's fault. She can't afford the clothes she wants? Husband's fault. He's just so unfair. How could she not be better off without him? She's strong and pure and good and she needs to break up with this loser.
Oh, the husband objects? He doesn't want a divorce? That's just bullying. He's promising to give her more say? It's just lies. He's asking how she'll pay the rent without him? Scaremongering. Of course you can pay the rent. Sure you may not earn enough to pay all the bills each month and you've both been relying on the credit card, but selling off the family silver will take care of that.
I could go on but you get the idea. The ultimate legacy of Salmond's failed campaign is that a significant chunk of the Scottish population has bought into the idea that they're somehow superior or morally better than the emotionally deformed English, whereas such feelings were not previously widespread. This is a toxic legacy that could take generations to resolve. It will certainly not make anything easier in future.
