"And all that matters is that lobsters want to be free to live their natural lives just like us, not cooked alive and eaten. Sending a yellow lobster to an aquarium while killing the rest isn’t praise worthy except in a society that fails to grasp the concept that all animals matter equally."
But people do care intensely about the color of their various pets and often choose one or the other based on color. Should we stop that because of the actual real-world human problem of racial prejudice?
Even with respect to human beings, we have lots of color preferences that aren't part of the race-prejudice problem. You might love seeing a woman in a red dress. You might want to dye your hair blue. You might want to see multicolored tattoos on other people's arms. You might adore Elizabeth Taylor because her eyes were a color that it seemed nobody else had.
Are all these pleasures something about which we should become self-critical?
If you want to be be self-critical, how about being self-critical about your precious attention to your own morality — that wonderfully named sin called scrupulosity — and consider whether likening the everyday joys of color perception to the age-old suffering of racism is itself a racist error.
