Well, can you help me understand how the conversation was detoured in the first place? I tried to read it, but as mentioned I don't use Twitter so it's confusing to me.

If I read it right...a person posted a photo that turned pixelated Obama, a half white person, into a fully white person.

A person, who I assume is some ML expert, explained that it's because the training set used uses too many white faces.

A person replied very negatively to this answer, saying she's tired of it, that he doesn't listen, and talking about injustices in the world.

I don't think either of them are wrong, I just don't understand the leap. Turning pixelated Obama into some random white guy isn't a social injustice. I kinda felt like both weren't even participating in the same argument.
