//I suspect that you didn't really mean what you said...//
I most certainly did. I have stated my position on here many times. I have wanted the UK to leave the EU ever since that nice Mr Major signed the Maastricht Treaty in 1992. Since there was never any possibility of the EU changing the direction that the treaty set, I wanted out. Any advantages there were to membership (and there were some) were completely overwhelmed by the terms of that treaty. Couple that with the eastern expansion and there was no way that membership would ever be beneficial in the long term to the UK. I may have changed my mind if the EU had changed its mind, but that was never even a remote possibility.
// . . or, as it seems to mean in reality, to allow England to make the rules without having to consult Scotland, Wales or Northern Ireland://
The UK government has no need to especially consult the individual constituent parts of the UK when making decisions for the UK.. They have their MPs at Westminster and they can use them to lobby the government. If they find themselves in a minority, that's bad luck. One (of many) of the unfortunate manifestations of devolution was it gave the minor areas delusions of grandeur.
