u/IncestHarem

I found it annoying and self-sabotaging how much authors whan to make every girl in the harem equal amongst each other.

They make sure that no LI can be more important for the plot than the others, that no LI can act as even a little bit of a leader for the other girls, that the MC must have exactly the same feelings for all of them because otherwise he is a perverted monster.

This just means that the members of the harem can never be their own individuals they are forced to be part of the same collective. They can never drive the plot or be more for the MC than simple trophies.
