Sexual harassment

[BillyKaplan]

I mean, harassment usually has the connotation of power to it

Such power structures really don't have to be pre-existing. Not every person who found themselves in an abusive relationship was originally submissive to their abuser - these are things developed and groomed by the abuser over time and manifest in various ways. So you're not wrong in the statement I quoted, but you are in assuming that power is always there from the get-go.
