I'm worried that I'm about to be called a Nazi Sympathiser, but still: yes, of course a lot of crap went on in Europe and Asia also. The Japanese in WWII in particular have a great deal to answer for.
But if we are doing that, and reminding ourselves how awful the bad guys were in WWII, shouldn't we also note that the same "community spirit" lauded here was found there also? The Blitz the British people suffered in 1940 was horrific and gutted cities, and killed thousands. Its ultimate aim, though, was to break the will of the British, and at this it failed spectacularly. But for some reason Allied Commanders didn't notice this and thought that trying the same thing on Germany *would* break their spirit. So we ended up gutting many German cities in return -- most notably Dresden, but many others alongside -- on scales that completely dwarfed the British Blitz. Did it break the German people's spirit either? No. They, too, came together and resisted some utter devastation.
I am absolutely not meaning to understate the horrors of the British Blitz, or to devalue the spirit of those who endured it. But it's historically inaccurate to somehow portray such a reaction as uniquely British, let alone to go on and pretend that it was universal.
It shouldn't be deemed "unpatriotic" to be truthful. And it shouldn't be necessary to portray all British people in WWII as perfect in order to claim a moral high ground over Fascism.
