While I think some of the name changes going around the community at the moment aren't productive, it's not a good comparison. The black and white in black beans and white rice are accurate descriptions of their color. "Black" is not being used to signify that these are malicious beans, out to cause harm.

Neither is the malice of black hats associated in any tiniest way with anyone's skin color.

The black==bad is a fundamental feature of all humans. Black people also fear the dark and not the sun.
