Lemme stop this right here so we're all on the same page.
Lindsay, baby girl. You were not and can never be racially profiled. You were lucky to be born white. Nobody can deny that white folk have had it easier throughout history than those with more melanin. So there will never be a time where someone will say "Hold up. That chick is white...she's definitely shady."
However, you can be discriminated against for something you are doing or wearing. And I'm guessing that's what happened when she was stopped at Heathrow airport and asked to remove the headscarf she was wearing.
