I think back to the Nate Parker situation when his movie was about to drop, and his past regarding a rape came up. White people held off casting judgement initially. If you remember, they didn't jump on him right away. What made them go at him eventually is when Black women on social media gave them the green light. The reason those women gave the okay, was because they were in their feelings over Parker being married to a white woman. If Parker had been married to a Black woman, they would have had his back.
That said, regarding Obama, had he been married to a white woman, Black women would have rejected him. A large portion of Black women didn't vote for Obama based on his politics or views. They voted for him because he fit a certain ideal that they dream of. They see themselves as being accepted when viewing Barrack's successful marriage with Michelle Obama. A lot of these women will never get married, will be single mothers, will not ever have children, will be gamed on by numerous men throughout their sexual prime years, etc.. The irony is Obama campaigned with a slogan based on "hope". That's exactly what a lot Black women looking at his marriage needed. It's no coincidence now that he's gone and Trump is in office, the current narrative on social media is Black men being the weakest link. They lost hope.
