I think the thing that confuses the debate and makes the statistics seem weird is that nobody tracks the order things happen in.

Step 1: working-class black people are married and poor, but peaceful and gainfully employed

Step 2: some working-class black people gain higher qualifications and their pay increases. They start organizing and demanding equal pay. They're going middle-class.

Step 3: white employers get upset, that black people want to get paid as much as white people, so they mass-import a bunch of poor, underqualified foreigners, to break the strikes and drive wages down

Step 4: black men are increasingly unemployed or paid starvation wages, black women stop marrying them or file for divorce and marry the state

Step 5: black area full of fatherless children, organizing into gangs

Step 6: shoot outs go crazy, so gun laws are enacted, but don't help much

Step 7: rich white people (the same ones who destroyed the employment market for black men because they're actually a bunch of greedy, lazy fucks who like having a subservient underclass) show up and demand gun laws to stop the shooting and raise the amount of welfare that black women get as a reward for being a Baby Mama because They Care About The Children.

Places with high marriage rates and low male unemployment don't need those gun laws because they don't have the fatherless children, who run around shooting people for sport.
