Vanessa Feltz said the reaction to her claim Rolf Harris assaulted her during a live television interview has been "vile".
The presenter revealed she had been subjected to an outpouring of "misogyny and hatred" after telling the Daily Express about the alleged incident.
Harris, 84, was sentenced last week to nearly six years in prison for 12 indecent assaults.
"The kind of reaction I have had, I found so upsetting. I was upset by the outpouring of misogyny and hatred and you know 'who would want to assault Vanessa Feltz'," she told BBC London 94.9.
"You think if people react like that, you can see why people don't come forward. I'm 52 and I can handle myself so imagine if I was a seven-year-old child, or 12 or 17, Feltz added.
"I'm not saying just if it's someone famous, but imagine if it was your dad, uncle or teacher."
