Nobody who self inserts into escapist media actually admits to it. They know it's sad, shameful behavior so they deny it and make excuses like they're just "observing", but if the main character does something they don't like, or something they don't like happens to them, they get upset as if it happened to themselves.
For example, if a cute girl in a haremslop manga ever shows romantic interest in any male character besides the MC, all the alleged non-self-inserters will break down about being cucked and the girl being a whore. But how does that make sense? Why would a reader feel cucked by 1 male in the story getting female attention but not another? It's because they're self inserting as the MC. They want the MC they self insert as to get ALL the girls and view all other men in the story as competition who they don't want to get anything.
That's the entire reason haremslop is popular. If all self inserters liked doing was "observing" they'd be ok with watching a story about 5 guys and 5 girls pair off into monogamous couples and just "observe" each of their antics individually. But no, that's not what they watch. They only ever want ONE male character to get ALL the girls and anything else makes them cry and shit themselves about being cucked. Because they only character they want to see have anything good happen to them is the one they self insert as.
