Lots of people have mentioned stop and search and that is the tip of the iceberg. Serious but still the tip.
White privilege is being unaware of and never having to deal with what a black/ bame deals with on a daily basis throughout their life.
The daily tone of voice change, the daily assumptions, the daily micro aggressions, the daily othering. In some areas this may happen more or may happen less but it is there and it is daily as the person is black or bame daily.
The daily changes in the behaviour of those around you from the person on the till in a shop, the security guard, the drs receptionist or the teacher at your child's school. Sometimes it's little things, other times it's glaring and big and in your face but it all forms a picture of injustice.
Ie the bags searches at a place like legoland, the bame person waits in the queue watching whilst the 5 white families in front are searched very quickly, often with only a cursory glance at the bag and get let in very quickly. It's now their turn and their bag is thoroughly searched, even their children. The 5 white families children were not looked at, let alone given a cursory search.
The 5 families in front benefited from white privilege but they will not know it or realise it or understand it unless they were told and unless they came to understand and accept the daily experiences of bame persons.
All those who say what about male or class privilege are derailing. They absolutely do exist but a poor working class person has to face the injustices of being working class and poor and of being black. The white working class person has to face the injustices of being poor and working class only.
If you are female and poor and disabled then yes your life is hard.
If you are female and poor and disabled and black then you also face white privilege very day as you are black every day.
I really can't see why people can't get their head around this or do some reading about it and listen to bame persons and their experiences . White people need to stop the denial, its on par with holocaust denials.
It is historical, structural, institutional and individual injustice.
