What do you qualify as ignorance?
I’d argue that people use the word “racist” erroneously and ignorantly (though not really in the Lukaku case).
I can’t comment on the situation in Italy, I don’t think anyone not living there can, but in Britain people conflate the word “racism” with “culturalism”. Racism is, by its definition, the assertion of genetic superiority of one race over another (see Nazi germany for the clearest example). I would say that bar a tiny, fringe minority, almost no one in Britain thinks they’re genetically superior on the basis of melanin levels in their skin. Too many BAME politicians, doctors, lawyers, sportsmen etc for the argument to stand up. There’s clearly no superior race on the basis of skin colour, it has been demonstrably proven.
Instead, people assert the superiority of their culture over another, which is why your Tommy Robinson’s etc target Muslims almost exclusively. They’re not complaining that they’re brown, it’s the Koran, the Niqab etc that draw their ire.
Race, culture and the conflicts they create are complex but the situation is improving, despite the rhetoric to the contrary. The Britain of my childhood was vastly more racist than the one of today, but progress is slower than we’d like. However, when you’ve got an ageing population and more old people than ever before in human history, and the completely undiscussed impact that has on the speed of social progress, one can’t expect things to improve overnight.
Either that or I’m dense, unthinking and completely ignorant...
