Your MC is an non-talking, non feeling tool meant to progress the plot. There is nothing to empathize with regarding the MC. You self-insert because of how barebones the MC actually is.
Because brown people had to insert as a Jap or white until gen 6, and Girls started this franchise being forced to play the Male, never mind brown girls, we don't have as much of an existential crisis when deciding who to play as.
We play as who we like or who we can, just like how we started.
