Firstly, it is important to recognise that ‘othering’ is an important political strategy to make it easier to justify wars and unjust distribution of wealth and access to basic necessities. During the war on terror and the unfortunate series of events following Septermber 11, 2001, in order to put a face on the villain, the headscarf and any form of wrapped headwear became a symbol for identifying these ‘villians’ or ‘others.’ Therefore, a headscarf on a woman's head became politicised and associated with Islam and terrorism, even though white American women have worn headscarves through out history, with notable examples including Audrey Hepburn and Jackie Kennedy in the ‘60s.
As far as the politics of Black women in America goes, it's beyond the scope of a few sentences to explain the complexity of how Black women have been oppressed under racism laws, from once being forced to wear headscarves to now being questioned for why they wear it.
That being said, there is also an issue of sexism between the cultures that follow Islam where, like American culture, they find it their duty to control how women chose to dress.
As a Muslim woman, I get to choose what I want to wear and when I want to wear it.
Unfortunately, there's no other way to exist, except constantly under the scrutiny of those who impose their judgment on me, and me having to ignore them and follow my own path.
