It is easy to get results to surveys like this by asking leading questions, which I believe has occurred here. I do not believe the results are genuine.
I cannot imagine a single person saying they are unpatriotic because of our "broken society". But apparently 20% of respondents said this was there reason.
If you asked English fans will the be supporting the England football team in the World Cup, then I would expect to find we are one of the most patriotic nations in Europe.
Wikipedia describes "This England" thus
// The magazine maintains a strongly anti-European stance and is seen by its critics as arch-conservative and reactionary. It features articles against metrication, the European Union, multiculturalism and other issues which the readership may consider threats to English identity. In the 1990s, it lent its support to New Britain, a very small right-wing political group, which it praised as "the organisation which is campaigning for a complete revival of our country". //
So little surprise that its survey result blames political correctness and immigrants for our so called unpatrioticness.
