(That is, before they get punished)
And supposedly grown assed men feel powerful watching porn because they don't have sufficient imagination and still have problems when Mommie says no or not yet - and they don't usually have to worry about getting punished afterwards.

But there's a really fine line between the fantasy of power over a character and actual abuse of power over a person.
There's visceral anger urges in all of us we don't like to admit we have, and we all have different coping mechanisms, much of which is through fantasy, that keep those urges in check so we don't inflict that anger on or otherwise harm other members of our community.
Imagining situations with other people (or archetypes/characters) you desire or hate may be unhealthy or distasteful, but publicly humiliating actual people by taking and manipulating their words, art, or image against them is literally assault, even against public figures once the action goes past satire.

Simplistic answer to complex individual emotional control issues, but pretty much what I've observed.
