I understand all that. Everyone & every area has problems, has Liverpool been more harshly treated than the N.E? I doubt it (you will probably prove me wrong with numbers). To be anti-English because of few years of a govenment you don't like vs 2000 years of history seems like a bit of an over-reaction. Obviously its your perogative but by the same token you can understand why it rubs people that are proud of their country up the wrong way.
The scouse not english thing is a bit cringey, as often it's partaken in by Liverpool supporters who are not from Liverpool and have no connection to the city. I'd also say, the southern fanbase of LFC are a committed to the "ingerland" team as just about any other fan base so it doesn't make any sense.
To me it seems a bit of a false argument re the north east. I suppose it would depend on the metric. The fact that a predominately tory government treats another area similarly badly doesn't disprove the validity of our own disagreement.
Recently some data showed Liverpool council has been treated the worst out of any councils. You've had memo's to try and run the city into the ground, the cover up over Hillsborough and how the government screwed us over re Heysel. Yet the response of most of the "ingerland" tools when it's put to them is basically that we are whinging.
That's the problem really. The cultivation of English identity is basically a continuum of southern knobheadery. It's the priority status of the city of London at the expense of others, to the monarchy (based in the south) to public schools (again mostly in the south) to a parliament in the south, filled with mostly people from the south. It's upheld by thuggish blokes from the home counties with union jack and st georges tattoos. If England had 2000 years of history, you'd have to concede these people represent the very worst of it.
Liverpool as a city is a relatively modern city (probably own 200 years of real history in that time). From moment one it received very little support from the governing bodies of this country. Within that context, a counter hegemony has formed and it's nationalism and stories are a far more compelling one than the English story.
That being said (ironically enough) I have grown sympathetic to English history recently. I've been reading a fair bit around the Normal invasion, and how the context of Englishness against their Normal rulers remained strong and even motivated the English Civil War, Parliamentarianism and Republicanism. The monarchy were seen very much as descendants of our French overlords and traitors. Perhaps that's how we should view the modern "nationalists" who stand very much in that Norman tradition, as opposed to the previous English tradition that exists?
Who knows, either way I'm an Evertonian first, second third and any number of numbers after that before I'd even consider being English. I'd say English people disliking scouser because of what a group of people with no connection to the city feel is a tad embarrassing, but then little surprises me anymore.
