A lot of things are supposed to happen and don't. Like systemic racism, something that people like you think just magically disappeared because laws were made.
Mitch McConnell is 78. He was 22 before the civil rights act was passed. He is a jim crow baby from Kentucky, Trump was 19 when the civil rights act was passed. Biden 22. Pelosi 22. Grassley 27, Manchin 18, Reagan was 55, so when you try to pretend that racism ended when people alive today today were living practioners and believers in Jim Crow, you are really purposefully ignoring reality.
People here grew into adults during Jim Crow, were believets and are still mad and resisting the laws. So it's time you faced facts. Blacks continue getting backlash because blacks led the civil rights revolution.
