You know what I will never understand, there is so much offence at just being told this word does not describe the experience of white people. The truth is, that white people would never willingly take on systemic, institutional or the levels of individual racism that poc face so why is there such a desperation to use this word? Do you think this is a club and there’s some kind of benefit for joining?
If a white brit gains an accent from living abroad, they can take elocution lessons and lose it. If they get grief for it, that is xenophobia not racism.
If a white brit finds that they are experiencing Islamophobia due to wearing a hijab, they can take it off. That is Islamophobia not racism.
There is no element of choice in racism. Lastly no, white people who are not Brits do not face institutional or systemic racism. The white other group as far as I can recall, has at least better health outcomes and more wealth than white Brits. Again, the prejudice they face is more than likely to be xenophobia.
It is so unhelpful to attempt to amalgamate all these experiences into one group. It makes research harder. It makes it harder to articulate the differences in experiences and it makes it harder for some forms of prejudice to be tackled in their own right.
