I am on neither side in this, for different reasons.

I wonder though, just to put it in a UK perspective. Just say 60 million africans were to decide that the UK was their ancestral homeland, because they are animists and at one time, the UK was pagan - so that makes the UK their homeland. So they descended on the UK, bought up land by the hundreds of acres, murdered their way village by village, town by town, which what a surprise, caused the British to flee to safety - then the Africans declared that since this land was empty, it is now the African pagan homeland.
The EU in support tried to invade, but the Americans came down firmly and biased on the side of the Africans, because they knew no president would ever get elected without the African American vote - they supplied the Africans with huge monetary assistance and weaponry - and the EU was not only repulsed, but large swathes of northern France, Belgium and Denmark were occupied.

Now, despite the UN calling on the Africans to withdraw to the land they were given (What used to be the home counties), the Africans refused and started building towns all over France to consolidate their hold.

Add to this, they build a concrete wall across the north of Europe, which happened to cut off the remaining British from food supplies, and when they have to cross this wall, they are subjected to random beatings. The British and French towns as they were cut off deteriorated into slums.

The Africans in addition grew rich with American help, and helped to destabilise the neighbouring countries, leading to huge anger in the region.

Then every single time anyone dared to criticise the Africans, or try to point out that they had no genetic relation to the pagans who used to live in Britain - the Africans would whinge that this was racism due to the slave trade years ago..

Well, put in that position - would we be a bit peed off?

Not supporting either side as I said, no-one in their right mind should think Hamas wouldn't put the place into the same position as Saudi or Iran if they had the chance, but thinking - maybe things aren't clear cut in that region
