I have no idea why anyone would defend this article because they can show some particular examples of white women who are violent.
Of course you can/ You can find particular examples of every group that is part of the human race being violent.
But when you make a statement about a group you generally have to show that it applies to the group as a whole, or some large portion of the group, or more than it does to other groups.
The implication of a statement in a magazine that white women are violent, tespecially one that goes on to speak in generalisations, is that white women are more likely to be violent than one would expect based on their numbers.
Which the article simply hasn't shown to be true.
It's the same as if someone showed that actually, men are not more likely to be violent. If that was shown to be true it would be very misleading to say that men (as a group) are violent and I would hope, if the evidence was strong, that people would stop saying it. Though in that case we'd have the excuse that there had been good reason to think it was true.
We have no evidence that white women are more likely to be violent than any other group of women, or more likely to be violent to non-white women than other women. They certainly are not more violent than any group of men.
I'm fairly shocked that it was published in a reputable magazine.
