Is it their culture that makes them this way?

It’s because poor people on poor people is the biggest source of crime and whites are so poor

Humans killing Humans who knows why.

But whites are killing other whites at a much higher rate than any other race.

Are they just naturally violent, it is their culture, or is both? And more importantly, what are the good Whites doing to stop it?

Depends on who's fiddling the statistics with the DEFINITION of White. In some studies Hispanic-Americans are labeled White depending on how the groups commissioning a study WANT the results to turn out.

But whether or not that is the case -- and statistically it does matter -- Whites are at least for now still the most numerous population inside the United States and so naturally they collectively commit the most crime in sheer numbers against their own kind . . . in spite of the constant leftist propaganda insisting that they primarily commit the most crimes against minorities.

There is a certain group, however, that routinely commits fifty percent of the violent crimes in this nation period . . . and they-- oddly enough -- are NOT Whites . . . no matter how much leftists WISH that it were so.
