Most black americans, and most white americans, do not have any conflict or negativity toward any other race. But there is a small number of violent criminals.
There are some black gangs where new gang members get more reputation and credit within the gang by raping and murdering white people. Extra credit for how innocent the victim is, they mostly go against women and children. This is something that exists in some places in America. This is not only black gangs who do this, there are also latino gangs like MS13 who do the exact same thing.
The largest amount of violence is done by black americans against other black americans. If a black person gets killed, more than 93% of the time it was another black person who did it. Young black men in Chicago have killed so many other young black men, that the number of deaths just in this one city is more than the number of American soldiers who died in both wars in Iraq and Afghanistan.
Department of Justice statistics show that between 1980 and 2008, black people did more than 52% of all murders when they are only 13% of the American population. Most of these were by black men, who are only 6.5% of the population. But not all of the statistics say whether it was a man or a woman, just says the race. In 2012, white men were 38% of the population, and they did 4,582 murders. In the same year, black men were only 6.6% of the population, but they did 5,531 murders. So black men were 6.95 times more likely to do it.

"As for interracial violence generally, blacks disproportionately commit it. Between 2012 and 2015, there were 631,830 violent interracial victimizations, excluding homicide, between blacks and whites, according to the Bureau of Justice Statistics.
Blacks, who make up 13 percent of the US population, committed 85.5 percent of those victimizations, or 540,360 felonious assaults on whites, while whites, 61 percent of the population, committed 14.4 percent, or 91,470 felonious assaults on blacks.
Regarding threats to blacks from the police: A police officer is 18.5 times more likely to be killed by a black male than an unarmed black male is to be killed by a police officer."
