Gosh, what a complicated view of the world you would have to have.
By that logic, you're absolutely fine with 90% of the world justifying resentment and animosity towards the British? Should we hate the Irish? What about the Japanese? Was it OK that we signed Ohashi? Why did he get a visa?
Should we hate all Russians? What about the Austrians? Feels like they get a pass. Is Andreas Weimann a Nazi? In living memory? Will it be OK for Tuchel to take charge of England in 20 years? That should cover the living memory part.
It's a good thing my great, great, great, great grandfather died before I was born. Otherwise, I'd have a serious complex about the war of 1812.
