Good job being a pedant. When you see people online complaining about whiteness? This is what they mean. Who do you think came up with the #BIPOC hashtag on social media? Spend more time listening when people talk about their own experiences. It's the least you and me can do.
Edit: come to think of it, do you know why the female-protagonist tag exists? Because representation used to be a major problem in games. Likewise with LGBT representation. That's the common trait making both necessary. It's not about gender as such, or who you can romance in the game. Other tags may be more descriptive, arguably, but these are not meant to be. Not all tags are equal, or exist for the same reason, and that's fine.
