I think, ultimately, the response to Anthea is "meh!" The agencies to target hate at are the television companies who employed her at exorbitant salaries, throughout the nineties, for no real reason of mass appeal - they were foisting her onto us anyway via the lottery shows and 'Pet Rescue' etc.
She was one of the first big money presenters, way before Wossy and just before Evans I believe, commanding fees of millions of pounds purely on her "girl next door"-ishness.
She was talented at reading an autocue, lifting her chin up, grinning and rousing dads from their slumber during her GMTV tenure, looking like Eamonn Holme's defence lawyer when sat next to him, but quashed all suspicions she was an intellectual of any kind when she opened her mouth.
She is a relic of an age when TV "pressennahs" had never had it so good, but she is no great artist, actress or expert of any kind. It is this neutrality, her portrayed vaccuity that limits empathy for the woman. When she tears, tantrums and holds forth on 'Hell's Kitchen' we are left wondering "okay, interesting - but my mum could have effing done that for a hundredth of the fee!"
Anthea, Carol Smillie and a whole host of other attractive thirty-to-forty something women maintained the same role as a kind of Doctor Who assistant throughout the blockbuster reality and game show boom of the nineties. They scowled, frowned, grinned, whispered asides and pointed, translating the Handy Andy or lottery rep at their side for a generation. They were there to be dummies' guides, setting feminism back a couple of decades with the implication that they, ultimately, were the dumb leading the dummies.
This category of female presenter did themselves and their kind more harm than good, revelled in vaccuousness and made it a sassy talent. They gained pots of money as a result but cannot return to the well so easily to replenish their pots.
As experts move into the middle of the frame, as exemplified in BBC's 'Coast' or with the likes of Ramsay and Kirsty Alsopp, pieces of human set dressing like Turner become obsolete.
