Looks to me like poorly thought out mush with a few glaring gaps in details, such as vague "family" and "community" and worrisome undefined scolding about "identity".

The EU/unified Europe as "unrealistic and harmful as the dismal communist project" - well, the UK has been part of the EU for 45 years - a few years longer than the doom and gloom of the fated Iron Curtain. The UK no longer looks as bleak as the grey landscape that inspired Bowie's 5 Years or Diamond Dogs. UK industry and competitiveness are doing fine (at least from London and ither modern centres). The UK/Ireland's nasty "troubles" were resolved in context  of a greater EU to steady things, while Scottish grievance stopped with devolution rather than full independence. The Shengen Agreement took place 33 years ago, so yes, Europeans can drive or fly to Sweden and Estonia and Romania and Spain w/o stopping, but they all look and act quite distinct - no need to test them for cultural uniqueness, and the Brits who've lived in Southern Spain for decades still seem British, believe it or not, though road ordinances have been harmonized so stop is still on red, non-UK/Ireland drives on the right, and we've largely got wall adapters (British being the bulkiest) and railroad gauges worked out.

And the authors seem sure the 2-party split is destroying the UK, but have absolute faith in a far-reaching referendum passed by only 3.8% mentioning nothing of huge documented lies and illegal monetary and foreign support (including Americans Steve Bannon and Robert Mercer, it turns out, along with Russian bot spamming). That 3.8% is oddly enough roughly the change in support that a few million dying-off Brexit elders and new pro-Europe adults make up in the ensuing 2 1/2 years of Tory incompetence in carrying out what they assured would be profitable and easy (assisted by the sadly lack of glee in restrained Jeremy Corbyn when his Labour government could be helping Conservatives wear this fiasco around their necks).
