(CNN) -- Shameless. There's no other word to describe Monica Lewinsky. Sixteen years after her affair with President Bill Clinton became public knowledge, she's returned to the limelight with a campaign against cyberbullying -- of which she claims to have been "patient zero."

Ignore the fact that she was patently not the primary victim in the Zippergate affair (poor Hillary Clinton was) or that any comparison with someone suffering a disease, especially at a time when people are dropping dead from Ebola, is tasteless in the extreme.

What's most depressing is that when she rejoined the public stage, she said she was inspired to speak out by the story of Tyler Clementi, a student who committed suicide after a video of him kissing another boy went up online. Young Clementi was the victim of societal homophobia as well as an invasion of his privacy, and his death makes any comparison with Lewinsky's self-imposed troubles ridiculous. Moreover, Clementi died in 2010. Lewinsky has decided to revisit his cause in 2014, suggesting that the timing may have less to do with him than it does with Hillary Clinton.

And, of course, this will be embarrassing for Hillary Clinton. Lewinsky has joined Twitter, which will allow her to make uncensored remarks in the course of the 2016 campaign. And Lewinsky has also lashed out at the way the White House machine trashed her in its desire to protect Bill Clinton's reputation (as it was paid to do -- she had an affair with the President of the United States, not an anonymous bank manager no one gave a damn about).

Another view: Stop judging Monica Lewinsky

All of which will give ammunition to Hillary Clinton's critics on both the right and left. The right won't have to waste its own resources reminding people of the seedier side of the Clinton years -- Lewinsky can do that now. And Democratic opponents to the left of Hillary Clinton will rejoice that someone is perpetuating the narrative that the Clintons are gangsters who toy with the lives of others.

Lewinsky's new cyberbullying angle is inspired: A significant number of Hollywood liberals must live in terror of unflattering/undressed photos of them getting out online.

But while Lewinsky grabs some TV time talking about her own liberties, she forgets those of her fellow sisters -- the mistreated wives. Imagine that your husband was caught cheating and the contents of your marriage were discussed every night on television. Would you feel happy about his mistress reappearing 16 years later to drag the whole thing up again, and even to play the victim? Does Hillary Clinton not have a right to put this scandal behind her and have a political identity separate from her husband's?

Lewinsky says that she wants to take on the "shame game." But what she did all those years ago and what she's doing now makes her a perfect candidate for a good, old-fashioned shaming.
