An old white man should listen to black people about what Obama did. That includes you.
White people talking over the voices of black people and "explaining" the issues that affect black people to black people is actually a very common trait among white progressives. It's so common, black comedians get their audiences rolling with laughter with jokes about their white fragility, such as:
“White people be like, ‘I’m not just white, I’m: 22% Irish, 18% German, 28% Italian, 30% French, 2% Milk.’”
Sanders is recognized for what he is by the black community.
