It was fashionable at the time within the black community.
I never said it did. I also didn't say that my brother was 'blacking up', but that it might have been construed that he was. If anything, it was the influence of his black friends and black culture that influenced his choice of image, but I would say that it doesn't immediately point to him wanting to 'black' himself up.
This woman was interviewed and could be seen to avoid the question of whether she considered herself African American. In a separate interview, she said she didn't consider herself African American, but she did consider herself to be 'black'. I believe she also acknowledged her Scandinavian and native American heritage as well within official documents.
Given that she is identifying with a racial label 'black' = a social construct, and not associating herself as being African American = ethnicity, then you would need to question how much of a 'lie' she's really making by identifying herself as being 'black'.
I never said that every person was. In my experience, and correct me if I'm wrong but, those type of (highlighted) facial characteristics are very common within African/Caribbean features. Much in the same way that epicanthic folds are very common within East Asian and Southeast Asian people. But that isn't to say that all of those people have this, as some also have double eyelids. Epicanthic folds can also be found within European populations, but I don't think it would be perpetuating a myth/stereotype to say that it is common to East / Southeast Asian people. Otherwise, to act all indignant about it risks falling into the being PC / trying not to look racist camp.
