Claire is undoubtedly treated differently due to her gender. The kind of bile reserved for her by "fans" hasn't been directed at the likes of Ron Dennis, Eric Boullier, Ciryl or other controversial team bosses. And I firmly believe that is because Claire is a woman.
That said, yes she deserves criticism for the state the team is in. She oversaw some great years, and is currently overseeing some awful times. We judge her ultimately on whether she's able to turn the team around. Would you judge Ron Dennis solely on 1994-6 when the years were very lean?
Dennis was coming off a works contract and building on a new partnership, first with Peugeot and then Mercedes.
And while I would certainly cut him some slack as the cars were still podium worthy in those years, Marlboro judged him and went with Ferrari instead. After the longest, most successful partnership in F1.
So yes, even Ron Dennis isn't above judgment as shown in 1996 and later by him actually even having to leave McLaren.
I don't get why when a woman is judged just like men are (because equality), some people pop up to defend them from "unfair" accusations because any criticism must be because she's a woman. And if you think Claire Williams gets more bile than Boullier or Abiteboul I suggest you actually read those threads. In fact, I would say you are treating her different due to her gender, protecting the poor woman from the harsh fans, while male managers are fair game in these threads.
Is anyone claiming Claire Williams is unfit because she is a woman? I thought we were debating if 2 years of failure without signs of improvement was sufficient reason to sack her? Boullier got the axe despite overseeing major restructuring at McLaren. It was felt that he wasn't part of the solution or credible as a manager any longer. I would say Claire Williams is now at that point. If Williams don't improve markedly in 2020, can she still lead the team?
