I find this remark strange:<p>&gt; 3. I thought about filters for sex and race at the same time, so that you could compare say, black female versus black male. But I liked the simplicity of one filter at a time better.<p>First, I got surprised why setting ethnicity erases sex.<p>Second, morality varies a lot with sex. So putting in the same basket male and female is, at best, trashing important information.
