Do you know why I can vote? It’s because guys voted for women to be allowed to vote. They had the power to decide otherwise. Instead, they paid attention to a strong movement and in 1920, women gained the right to vote in the U.S.
Do you know why slavery ended? Because in the Civil War, 838,358 union soldiers were willing to die. Most of those were white, but some were part of the 190,000 black soldiers who joined up in the later part of the war. Millions more were wounded. Surely some of those didn’t support ending slavery but they didn’t leave the ranks when the Emancipation Proclamation came out.
You want white attitudes to change but you don’t want any white people talking to other white people about it. Even thinking that this will work is just plain silly and it is what it’s meant to be. It’s deeply offensive to people who would help your cause. You don’t want to see any white faces or listen to any white voices. You want a new segregation. That’s pretty vile.
