Not everyone sees it that way. I for instance think the agenda and politics behind the presentation and the way the casting went was based on identity politics and virtue signalling, and a mellenial ploy, coupled with my disdain for the acting style of Whitaker is why I think the casting of her was a big mistake. Would they have cast a different woman, and left all the divisive preachy political stuff behind, I would think better of the new season coming in Oct. But for now, no..I see this as a disaster and a continuation of dogmatic ideological memes forced into the series, which will continue to drive many hangers on from the traditionalist wing of the fandom away. Same as had been done in the Capaldi era, and really started by season 8 in Matt Smith's reign. There are other legit reasons for being skeptical of the new series that has nothing to do with Jodie Whittaker's gender.
This regardless of how one feels, percieves, and suspiciously suspects that the reason is sexism. It's hard to know what's in a person's heart, even trying to link their comments to something with no real proof. I feel it's better to leave labels behind in that instance, and debate on substance.
