I think it's a significant enough event in the war, depending on their criteria - do they for example mention the end of the siege of Leningrad or the battle of Tobruk or the start of the Blitz? If so, the uprising should be mentioned.
Poles were Hitler's Holocaust accomplices
Some were.
Enigm
A largely British achievement.
better kill record in the RAF than the Brits
Perhaps because the Polish contingent was a very small motivated bunch of pilots with pre-war training, rather than ordinary young men who joined up after hostilities started.
the contstant inclusion of homosexuals amongst Hitler's victims
The 'constant' inclusion? Not a penny's compensation was paid until relatively recently.
but in some cases Poles, who lost many times that number,
Remember that the number of LGBT among the Poles who died at German hands (since intelligentsia were a particular target) is higher than the statistical norm among the population as a whole. Intersectionality, y'know...
Nevertheless, There are many, many monuments to Poles who suffered.
why does Britannica omit Yorkshire Day celebrated on 1 August, too, which is an extremely important event in the world?
Hugely important.
You need to come to realise that Poland isn't and never has been, nor will be an important country....sorry, it was once, my mistake but that's coz Polish royalty married into the Lithuanian royal family
Pępek Świata to nationalists. It's called the cultural cringe. That and a pathological need to blame others for, well, everything...
It rather reinforces stereotypes to see someone worked up that a foreign encyclopaedia doesn't reflect their own outlook on their own country's history. Perhaps Pol3 would like the Encyklopedia Powszechna's entries on Germany to reflect a particularly nationalistic German viewpoint. Perhaps we should give the Spanish a veto for the entries on their civil war. But which lot of Spanish?
And I reserve the right to edit any Polish book on my home town...
