I think people are being simplistic saying 'hate racism'. I think we're all racist if we analyse it enough. If you see groups of people in the street they're almost always with friends of their own colour, and people almost always prefer to live in areas with their own sort of people- I think that's racism but we almost all do it. Maybe it's genetically programmed to be racist and 'keep with our own sort' for 'survival of the fittest'?
Also it seems to me that a lot of African's are pretty racist ( e.g. the Hutu/Tutsi massacre in Rwanda, and this recent bus hijacking in Italy
https://www.bbc.co.uk/news/world-europe-47642298). Likewise a lot of child grooming gangs seem highly racist towards white kids.
I don't think people should shout racist abuse to each other, and there shouldn't be racial discrimination at work. On the other hand I can see that the white people have been mostly safe in a white Europe for thousands of years-it might be racist to want to keep it that way, but arguably it's common sense to avoid racial attacks against them?.
I don't know if this woman was guilty or not, but I think it's unfair she was found guilty on the balance of probablity -50.1% is too weak a legal test for shoplifting so it's certainly not strong enough for this charge.
