A few points for discussion:
- Slavery did not only happen in America (or the then forming America). It's still happening. White (along with other colors and nationalities) slavery existed, exists, and includes things like human trafficking and sexual slavery.
- I'm sure the counter point to this would be that it is set in Detroit and thus should be tuned to American history (even though I'm sure sexual slavery is happening in America, as well) but for argument's sake, the "lens of people who are oppressed and enslaved in 2017" may not be just what you think it is.
- Everyone can be discriminated against. Everyone. If you put a white person in a community of, predominantly, another ethnicity, that person will probably be oppressed and excluded in some shape or form.
- Androids are treated as objects (usually): much like how people are when they are reduced to slaves, mere outlets for sexual pleasure, etc. That can happen to any ethnicity.
- The realization of whitewashing in media is important and something to be corrected - at the same time, one has to be careful to not snap immediately to the other extreme and see everything as a foul. That goes for anybody including myself. It seems prudent to get the author's take.
