That's not at all what intersectionality is. It's just a name for the fact that the hardships you face as, say, a black woman isn't the union of the hardships of women and the hardships of black folks. They don't exist independently. This was an important idea because feminist movements focused almost exclusively on white women and it assumed this was fine because "rising tide raises all ships" and that white women had a better chance of having their voices heard -- but it didn't shake out that way and this was the reason.
That's the reason today there's a lot of focus on black trans women because activists are trying not to repeat this mistake.
