Yes, it's silly, as in a waste of time. As in you calling for it is a waste of breath. As in you might as well call Angelina Jolie and ask her to blow you.
People don't resign in the wake of controversies like this anymore (or if they ever did, see, eg, Teddy Kennedy). They just have a presser, maybe do some BS rehab, and wait for the next controversy to knock them out of the headlines. In 2 months, Weiner's weiner will be in the long list of people we talk about when the next guy's story breaks.
The guy's a pathalogical douchenozzle and compounds it by being an arrogant prick. Shortly he'll find Jesus and try to reinvent himself.
