I agree “white” itself isn’t really a culture. Irish and Italian is. However I agree and disagree with the idea of whites having a shared experience. As of now, all white ppl may have the freedom of not being discrimsted against or benefiting from white privilege, however groups who arrive in the early 1900s like Irish, polish and Italians were discriminated by Anglo Saxon protestants. However overtime they were assimilated into the white umbrella. Btw this is clearly the North American perception and notion of race. What are your thoughts ?
