I'm assuming things? The claim I'm making isn't even a crazy one. The vast majority of Diasporic Africans had kinky hair. This includes Africans brought to the US via the Atlantic Slave Trade. The majority of African American lineage can be traced back to these people. So then, even accounting for interracial relationships and conception, it's not crazy to think that the majority of African Americans have a hair texture with some type of kink in it.
There's even a widely accepted chart of the different types of natural hair textures. Notice that of the 9 established hair types, only the first two can really be described as possessing no kink.
You're also making the mistake of thinking that all the girls I posted have the same hair type. They don't. There's
levels to kink, and yes, while there isn't a definitive survey of the hair types of black women in the United States, it's fair to say that the majority of black people have a hair texture with SOME kink to it.
Meanwhile, you're making a completely out-of-pocket claim (that African American women "don't have do anything" to have straight hair) and your sole basis for this claim is some of the girls in
your family.
