That is something you conspicuously failed to do dozens of times on this page. The other person is always missing the point, didn't read what you said, falling victim to one myth or another, disingenuous, irrelevant, fixating, making absolutely no sense, slipping in thing at the end after the red herrings, seem eager to put words in your mouth ...
It makes for super-tiresome reading. This is not a productive method of communication. (That was you complaining about the other guy yet again.)
Please consider that you are just one person among many on here, and that you may seem as ignorant, misguided, irrational, unfair, impossible-to-argue-with, prejudiced to them as they apparently seem to you. And please be more considerate in future. Be civil. Don't be snarky.
> Black crime rate being high explains black arrest rate being high.
Where is the causality here? Sure, there is a correlation and sure, it may be seen as a reasonable argument, but like your point before about CO2 not being a problem, you completely overlook that there could be many causes for the same event.
How is your fact about crime rates invalidating the position "there is racism amongst police forces"? The effect of the higher crime rates _and_ racism are not mutually exclusive.
But you choose to rather adopt a point of view where every situation can apparently be 100% explained by a single cause. And that cause is that black people are not "up the standard" -- whatever standard you are talking about.
Yup, that's racism.
