Its all rather unpleasant to be perfectly honest (I think you knew that). Lots of stock footage of WWII, photos of Winston Churchill on Nick Griffin's desk, etc. (I didn't check if the Spitfire was Polish, and I can't bring myself to watch it again). Its got all the usual crap about how great Britain is, and how much Nick loves his country, interspersed with some really nasty graphics. Universally aimed at the Muslim community. There's the "Immigration Open your eyes" union flag, and the cartoon of a woman in a burkha next to a map of the UK covered in minarets.
Architecturally speaking I like minarets. I'm less enamoured of Islam, but that's got rather more to do with my dislike of all organised religion, and the various brands of extremists who make the average believer hold their head in their hands. (Steven Green, I'm looking at you.) I'm not overly keen of the burkha either, but that has rather more to do with whether or not the woman in question has a free choice to wear it or not. Speaking to various Muslim friends over the years there's certainly nothing in the Koran that states its compulsory, its very much a cultural thing. And when it is a free choice I do not find it the least surprising that first, second or third generation immigrants choose to wear it, in order to identify more closely with their faith and ancestral culture. Especially when faced with the consistent islamophobic, anti-immigration rhetoric of the Daily Mail and co.
I like immigration. Immigration is a good thing, My grandfather's family came from Poland and Lithuania, via Canada. (I don't have a UK passport, but a Canadian one for this reason). In the wke of the leader's debate twitter is currently full of people pointing out why #iloveimmigration (I'll just repeat miss_s_b - "Freddie Mercury. 'Nuff said"). Our culture, cuisine, scientific progress, history, etc, etc would be very much poorer without it. The Huguenots came in as refugees, and within a generation had strongly influenced the lands they settled in. Wikipedia has a list of people who can trace their ancestry back to the Huguenots. Oh look. Winston Churchill's on it.
The broadcast asks what would our veterans think of multicultural "politically correct" Britain? Well as many WWII veterans were conscripts I think their views would be very diverse. I'm sure some thought Hitler was right about the Jews. Equally many others would have volunteered for the International Brigade and gone off to fight Franco in Spain had they been old enough, and of course there would have been all points between the two.
As for "Political Correctness" well, yes perhaps people go a bit too far in trying to avoid offending groups, who, had they been asked would probably wonder what the fuss was about. Mostly however what is reported to have happened, and what actually happened are usually rather different. Ultimately its about recognising that not everyone is a straight, white, cis-sexual, Christian male. And I think the country would be rather better if more people lived by that maxim, rather than any of the strange ideas they have about what constitutes "British Culture".
Ultimately were the BNP to get in virtually everyone I know and value as a friend or colleague would be made to feel unwelcome in the country that either they were born in, or have chosen to call home.
