I didn't produce bad math.

"despite blacks having been only ~1/6th the size of the white population."

Is bad math. The ratio of population has the same effect of black on white crime as it does on white on black crime.

I agreed with you that the image has bad wording yet you continue to divert attention to it even though it's irrelevant to the larger points.

If you reckon the image had bad wording, you didn't agree with me. It had bad maths. It says that the risk to white woman from black men was 64 times that of the reverse. The correct value is 1.9 and much of the difference between that and 1 is plausibly racism in the justice system.

The 64x does however give a valid scale to get a sense of the abuse behavior

Not or doesn't. You could argue that 1.9 x does, but you'd be ignoring other demographic factors of you were to attribute that to race alone.

because white women will still be their primary target at scale.

You should present some evidence of this.
