"Something the author should consider is the fact that most British people (myself included) don't consider themselves european."
And you have some statistics on that do you? Maybe the people in your little world but for those of us who have met more than, say, ten people in our lives I would probably say most people would punch you if you tried to tell them what they are or are not.
"We don't speak a latin language."
Neither does Germany (as one example), what's your point?
"We make few rules but we stick to them, unlike continentals who make many rules and ignore the ones they don't like."
Yes, like the rules Bankers have to adhere to, or Politicians when claiming expenses. And the few rules we stick to, how many laws does this country have? When you take a black taxi do you make sure the bale of hay is in the boot of the car?
"There are more differences than similarities."
Yes, that's a good thing. Go check out evolution. The theory, not the film.
"We just happen to share a continental shelf."
We could try and cut ourselves off of that if you wanted, I'm pretty sure we have the technology?
