She got owned on a Youtube video where a housewife took her to school
We've all seen that (well, not on Youtube - it was famous long before that).
Why should we have given the English-speaking, British-settled Falkland Islands to Argentina, a country that had only claimed the islands on paper and had never settled there? I'm no fan of Thatcher, and there were events in the Falklands war that were wrong, but it is not Argentinian.
I have heard an African-Portuguese bloke moaning about how it's all to do with slavery and it should be Argentina's. I just told him that it was settled by British people, without Africans or slaves or anyone, and that Argentina is hardly the best model of a multicoloured society. He had, like many others, fallen for the badmouthing propaganda that paints Britain in a bad light.
When Poland has such things to deal with, the Poles can really legitimately moan about being disliked in the world. I don't moan about Britain being disliked because it is just a fact of life.
