Nice try, but "black crime" (see 1st paragraph) is actually a thing that people study.

Now, if you wanted it to mean specifically racially motivated stealing, there's that too:

Also published by the federal government is the Known Offender's Race by Bias Motivation, 2009.[22] According to the Federal Bureau of Investigation Uniform Crime Report database, in 2010 58% of hate crime offenders were white (including latinos), 18% of offenders were black, 8.9% were of individuals of multiple races and 1% of offenders were Native Americans.[23] The report also reveals that 48% of all hate crime offenders were motivated by the victim's race, while 18% were based on the victim's religion, and another 18% were based on the victim's sexual orientation.[24] The report states that among hate crime offenses motivated by race, 70% were composed of anti-black bias, while 17.7% were of anti-white bias, and 5% were of anti-Asian or Pacific Islander bias.[24]

Oh well.

(To avoid misunderstanding, this comment is not meant seriously, it just serves to illustrate the offensiveness of "mansplaining". I just had to use an analogy, because offending men is not considered an offense.)

It is a pity your satire fell flat.

EDIT: Also, regarding:

I assure you that I am fully aware that sometimes also black people steal from black people, or white people from black people, or white people from white people, etc... but that is irrelevant here, because those acts just don't have the same qualia.

"Qualia"? Goals, motivations, and revealed preferences (that is, the things that separate "explaining" from "mansplaining" and from "splaning" in general) aren't qualia.
