On the surface, no. BUT if you go deeper, depending on your moral slant, the black magistrate could be seen as worse BECAUSE she knows how harsh and debilitating discrimination can be and would be expected to show more compassionate than the white magistrate. OTHO, she herself may see herself as subverting the system and balancing the scales in her own twisted way. She may see so many black defendants throughout the system get the short end of the stick, that she feels that by finding judgement against more white people, she is actually meting out justice. The white magistrate may be worse if you look at it from the perspective that s/he is not only feeding the existing system on injustice, but with each finding of guilty, making that system stronger so that it may do more damage. Within a system of white supremacy, white supremacist actions ripple further and damage more lives because the system amplifies the initial action. And that which does more damage in many moral systems is that which does more evil.
Why do you think people object to the hypothetical white judge being called 'racist' whilst refusing to call the hypothetical black judge racist, for the exact same actions, with the exact same malice, with the exact same power relationships over the defendants?
About 70% of people who die from intimate partner violence are women, so fatal intimate partner violence is gendered -- women are more at risk. Is it less morally evil to kill your intimate partner if he's a man, because at least you're not contributing to the 'toxic masculinity' culture where men feel entitled to abuse women's bodies?
I don't think it's less morally evil. Intentions are everything. That's why I find the sociological definition of racism not only inaccurate, but also morally dangerous. When a woman of colour, who hashtags #KillAllWhiteMen defends her actions by stating
I can't be racist, she is attempting to divert moral culpability from her morally abhorrent act. To say racially bigoted actions from minorities
don't really matter is to perpetuate the idea that -- surprise -- racially bigoted actions don't really matter.
Of course they matter. And it matters what they're called too.
Racism is racism is racism.
