Maybe if said men did not "run thru" little girls and then move on to the next target, it wouldn't be seen as evil...
I mean, you are comparing apples with oranges here. Seeking a 'dominant partner' implies the possibility of permenancy or at least honorable intentions and respect for the other person, whereas seeking a 'young and healthy female' infers objectification, a temporary arrangement (when one girl is no longer young - since we all age), and generally dishonorable intentions.
