What is Oluo's ultimate determination about whether it is alright to ask a black person if they are okay with their hair being touched?

Oluo states that under no circumstances is it okay for a white person, or any person, to touch the hair of a black person without permission. She widens this claim to state that this should be obvious, since no one person should ever touch another person without gaining explicit permission. However, she says, this rule applies even more strongly to black people's bodies due to the context of extreme oppression present within American history. When it comes to whether it was alright to ask a person of color whether you can touch their hair or not, Oluo encourages the reader not to take this action, either.
