Isn't some of this normal though?
When you see a picture of a classroom would you notice if there were no wheelchair users? I would, I am a wheelchair user, but I actually wouldn't expect everyone to notice, and I wouldn't think that was a major failing on their part if they did not notice.
I don't think we can be 100% aware of every single thing that affects every single person. Whats needed is the ability to listen when someone says something is a problem.
Why is it ok to suggest the entirety of a group feel one way about something? The few adverts I have seen that include black, mixed ethnicity, non-white people.. are absolutely fine, no more irritating to me than any other advert (And that is my overriding feeling about advertising, it is usually irritating!) - i can't speak for all white people, I am not all white people, nor do I know them all. I am sure there are some knuckle dragging arseholes who have an issue with it, but we're not allowed to throw them all in the sea!
By your reckoning, I am not experiencing white privilege!
My sister drives me a lot - we regularly get stopped because she looks like a 14 year old boy (And some may say drives like one at times), driving round in a fairly fast car often late at night.
I have to worry about abuse in the street every time I go out and this has been affecting how much I go out by myself following an unpleasant incident where a man came over to SPIT at me and tell me I am disgusting. When I was going out frequently I would experience something like that five days out of seven.
I have to worry about every single venue I try to access, because theres a good chance I can't go in, that I'll be told I can't bring my assistance dog, that I'll be told my wheelchair is too big, that I'll get eye rolls, sighs, all the way up to being screamed at to fuck off 'we don't want your type in here'...
I get it - it doesn't matter that my white privilege isn't much of a privilege, because MOST white people have it, and when the majority have it, thats an issue... but it is pretty galling to be told repeatedly that you have this magical privilege that in fact, you don't!
