I think all this talk of CoP falling afoul of the woke police is a bit of a red herring. Sure, it follows the history of a white American family through the twentieth century, but you make the good point that the things that seem to be provoking change mostly involve negative portrayals of certain groups. More effort will also be made to increase the diversity of people represented in existing attractions, but this narrative that CoP is on the chopping block for being too white seems like a bit of a dog whistle to me.
As for the sexist dialogue, my experience has always been that the audience laughs at its ridiculousness which I think is appropriate. Even if the reception has changed over time in accordance with changing values, it seems almost progressive for Disney to present a show about the evolution of the American family through the twentieth century that includes outdated gender roles exaggerated for comic effect.
Yeah, this all really ties back to the immense amount of sensationalism surrounding the JC changes and SM re-theme. To remove CoP (for what exactly?) would mean a litany of things for the park, and the park's customers. SM isn't being torn down, or having its ride system gutted. It's being drained, redressed, and ultimately retooled for future use while maintaining the most notable aspects of the attraction (aside from the obvious SotS theme), more specifically in the eyes of the general public, and/or more casual fans (TWDC's usual target demographic). To bulldoze the entire attraction completely, would cause major uproar beyond anything I could possibly comprehend, and would leave the fandom divided for decades to come. They're not trying to steer themselves down such an extreme path. This isn't Universal, this is Disney, and with Disney comes legacy attractions which have gained their own status within the company. Plus, I haven't actually heard anyone online complaining about CoP, in any sort of serious manner. Many love the attraction (some of which are fans who are defending the JC changes and SM re-theme), and for those who don't, find it boring and/or outdated, and have nothing more to complain about to move the needle.
Bottomline is, to remove CoP would cause an awkward division within the theme park community, alienate much of the loyal fanbase, and aside from that, there really isn't any reason as to why it would be deemed so problematic, any more than JC or SM seem to be for that matter. It isn't connected to any sort of problematic IP, and thus will not suffer the consequences SM had to suffer, for its connection to Disney's singlehandedly most infamous, problematic, taboo film of all time. This was the only fate for SM. The writing was on the wall for SM, even if we may have been blinded by the attraction's ability to separate itself from SotS's problematic aspects. If JC says anything, it's that we won't have to worry about legacy attractions being erased, but rather preserved for the long term with minor alterations. SM was a special case, period.
