That's streching it a bit, but then you must believe that slavery itself is not racist.
Did they not all believe the Africans were an inferior race? RACISM.
Of course slavery was based on the belief that one ethnicity or nationality was superior to others. Then they thought it was based on race, but modern scientific and anthropological thinking, we are all the same race. Hence why the word 'racism' is still used.
But the American civil war was about stopping slavery, i.e. different political thinking and ambitions, not about racism per se.
I don't like football but surely you mean 'own goal'.
Precisely, you knew exactly what I meant. You didn't argue that 'home goals' can't or don't exist, you knew exactly what it was. You pointed out that there are other expressions in common use.
Just like racism. Everyone, except for you, knows exactly what is meant. Whatever you want to call it, ethnocism, nationalism, racism, the eminent organisations all agree on the term racism to describe the whole bundle of 'isms'. They even describe the type of discrimination that are included in such behaviour as 'racism.
But you create a perpetual argument that racism does not and cannot exist, based on some outdated idea that the human race consists of different races. Or perhaps you still cling to the idea that there are substantial physiological differences between different ethnicities or nationalities.
Racism does exist, and the UN and other eminent organisations have defined it. If you refuse to accept their definition, it is you who is out of step, not anyone else.
