Groping was wrong, but he had every right to ask whomever he wanted for a date, compliment whomever he wanted, etc. Just because someone is in a position of power does NOT require them to stop being human. You spend 1/3 of your waking life at work — G-d fucking forbid you’d meet someone that you’re interested in. (And in fact, policies prohibiting relationships at work regardless of position have been held to be a violation of human rights in many states.)
Publicity-whore Allred and her army of hypersensitive minions are as bad as Filner himself — both exemplify the worst of American hypocrisy.
