Is white privilege real? To what extent?

[Mister Agenda]

You've latched on to one particular definition of a word (presumably the first one that comes up when you Google 'definition of privilege') that different dictionaries define in various ways, emphasizing the part of the definition that makes it different from other definitions, where the most common meaning of the word is likely found where different dictionaries agree.

I used the Oxford dictionary and Cambridge as they're the most commonly used and trusted dictionaries in England.

And I agree with everything you've said, my conclusion is that it's racially bias to attach the racial advective white before the word privilege if it just means advantages people have that others don't.

If you define privilege using the common definition than white privilege 100 percent exists, along with Asian privilege brown privilege Jew privilege Japanese privilege,
Black privilege possibly exists to an extent, world wide I'm sure there's a race somewhere with less educational, economical, crime rate advantages.

Yep. An example of black privilege might be that it's more socially acceptable for blacks to criticize white culture than vice versa, since the former is 'punching up' while the latter is 'punching down'. Doesn't mean a particular criticism of an aspect of black life in a particular region by a white person isn't correct, but it's likely to be viewed suspiciously, at least. Not much of a privilege, but it's not nothing.
