Were all Spanish people "shits" because a strain of deadly flu originated there?
Well it more likely originated in France (?) but most likely from China (!), so no ...

There's a big difference - people weak from malnutrition, injury, unsanitary conditions, proximity of farm animals all consequences of the conflict that wasn't their fault and made worse by mass migrations forced upon them - just unfortunate timing.
It's really not the same thing as a country that consistently has a poor human rights record and regularly shits on the planet and on wildlife (apart from Pandas, which I fucking hate).
But to show I treat everyone equally - the Spanish people are shits for allowing bull-fighting to happen.
