One of my students made an interesting point today. He said, "I have an idea for an invention; I want to invent black band-aids." So I told him that I'd already seen black band-aids before. And he goes, "No, not black band-aids, but Band-Aids for black people."
And I realized, holy shit! The band-aid industry is racist! Band-aids are skin colored . . . but only for white people! How have I never heard this discussed before?! Ridiculous.
