You're getting worried over nothing.
The fact is, blacks aren't inherently criminal. What confuses people is that blacks have a lower-than-average IQ, and low IQ correlates with poverty, behavioral issues, and crime. Thus, black people, who tend on average to have low IQ, tend on average to have criminal behavioral issues.
But that's just an average! When you start to break people of Sub-Saharan African descent down into smaller, more precise sociological groups, that average can change. Such is the case with Blerds - "black nerds". Yes, blerds are black, but more importantly they're nerds. Nerds tend to have average to above-average IQ, and to the extent that they engage in criminal behavior, it's usually just white collar and creepy-sex crimes. By their very nature, nerds do not conform to the overall average of their racial and ethnic groups - thus, blerds can no more be expected to engage in violent criminal behavior than the more typical white, Jewish, and Asian nerds.
Furries are a subset of nerds. They tend to have more behavioral and mental health problems than average nerds, and they're particularly dangerous around children and/or in any setting that may afford them a chance to have sex. So that's bad. But there's no reason to suspect that Blurries (black furries) would be any more, or less, inclined towards violent criminal behavior than your average furries.
Indeed, I would hypothesize that Blurries will prove to be less problematic than non-Blurry Furries, as Blurries will be more likely to be fur-curious, adult blerds, still in the early initiatory phases of furry indoctrination. Furry degeneracy is a process that takes years, sometimes even decades, to fully metastasize - while there will doubtless be a few hardcore blurfags who were groomed from an early age to be deviant little monsters, I suspect that serious cases of blurry degeneracy will be relatively uncommon, at least for the near future.
-edit- I seem to have misread the OP! How embarrassing!
I was addressing the problem of niggers ruining furries, but upon review, I believe the question was actually about furries ruining niggers. What a nigger move on my part; please accept my apologies for wasting your time.
But to answer your actual question, I'd still call your attention to the matter of relative IQ levels. Blacks are unlikely to become blurries if they're stupid; thus, their low average IQ would, ironically, inculcate them against the furry virus. I absolutely believe that a higher percentage of blerds will succumb to furfaggotry, yes - just as nerds of all ethnicities are falling, day after day, to the twin scourges of furrydom and LGBtroonism. But it will never become mainstream black culture.
(ar least, not until a generation or two after the Final Collapse, when everyone who wasn't killed by globohomo reverts back to tribal Animalism, and ancestral fursuits become important religious relics from the Before Times)
