"We" are the white majority who forced blacks into segregated project housing in the 30's breaking up integrated city neighborhoods.
"We" are the white majority who created the precursor to the FHA in that same decade to loan money to prospective home-buyers but specifically excluded blacks from the program allowing whites to move out of the city and begin building wealth while leaving people of color behind.
"We" are the white majority who through redlining refused to loan money to inner-city blacks so they could buy the housing that remained, and refused to loan them money so they could create businesses in their own neighborhoods. That money went to white people who bought up those properties and allowed them to crumble into slums and established what businesses existed while siphoning all profits out of the neighborhoods that generated them.
"We" are the white majority that created the GI Bill to encourage veterans to buy homes, create businesses, and further their educations but denied those benefits to black veterans.
"We" are the white majority who created impediments to voting that prevented those people from electing politicians who could have addressed those issues 70 years ago.
"We" are the white majority who, through urban planning, then cut those poor neighborhoods off from the functional parts of the cities they lived in by running highways along their perimeters.
You don't get to say "I didn't do it so fvck off" any more than the people trapped in those situationss "we" created can say it. They have to live with the consequences of what "we" did then. So do we.
If your 23AndMe established that you're 1/8 black because a great-grandfather you never met happened to be black then I suppose "we" doesn't include you.
