If I was being very generous, it's a way of pointing out that non-White people might have trouble doing these things and we therefore shouldn't judge them as a result (a little patronising and illogical). This angle is to help White people understand non-White people.
If I was being more realistic, it's a way of saying that things that White people might be proud of, or positive things people could say about "White culture", are bad because they are different and linked to "Whiteness" and non-White people don't have to feel bad for not having these things. This angle is to attack White people.
