From my point of view, and thisvis just MY experience: if any white person is confused about what the 'white gaze' is. Search on YouTube #whilst black. Examples: shopping whilst black, driving whilst black, bbqing whilst black, wearing natural hair whilst black, dating whilst black, jogging whilst black.
The list goes on.
Please don't be under any illusion that the WG is staring at a person of colour for longer than needed. In my opinion, it starts with harmful stereotypes and extends as far as police brutality against 'minorities'.
I'm waiting for people to tell me I have a chip on my shoulder (classic gaslighting response). I don't. But when you ask me why you should, as a white person, be offended because I want to be around people that have never posed a threat to me, well, there is your answer.
And it works the other way around, too. Look at Brexit. People were getting uncomfortable with the thought of more immigrants on this land that didn't look like them. They didn't want them moving next door to them.
I have heard the comment, so many times, that England is becoming a Third World country.
I could argue that SA, Australia, Canada, New Zealand are now, primarily, European countries but nobody wants to have that conversation.
It goes a lot deeper than most people are willing to dig and that's excluding the historic atrocities, that were 'lawful' that my ancestors had to deal with.
So, in conclusion, we are ALL wary of anything which has made us afraid.
