African American

Even minorities treated a middle-aged, middle class white woman differently than how they treated women of color. And it was usually very subtle, like the bus seat next to me would be the absolute last one someone would sit in. They would let the older white woman sit alone, sometimes even standing, instead of taking the seat next to me. When you notice subtle things like that, the obvious stuff really starts to stand out afterwards. That white people get offended or defensive when told they experience privilege in our society, I'm just awed how they can be so obtuse. White is the default, just like male is the default.
