HOW can these people be so stupid!
Ask any daughters or nieces, "How would you like a date with someone almost as old as your grandfather?" and their only reactions would be horror, revulsion, disgust, or stark incredulity -IF they ever spoke to you again!
I doubt they even feel old men HAVE a sexual identity at all.
So were I to ever encounter someone online who claimed to be some underage girl who would just love such a date, I think the only response would be, "I do not even want to know your badge number...Just keep up the good work!"
Yet, it seems every week we read about some self-destructive delusional moron.
