There is an incredibly powerful impulse among humans - and it is amplified in Americans - to imagine that everything is and always will be “normal” and that change never happens. Therefore, if something is happening, it must be OK simply by virtue of it happening. Even if a few years and a lot of gradual changes ago the thing would have been unthinkable, even if it would have once caused fury or despair, even if the individual specifically condemned the unthinkable thing. And since everything is always normal, anyone who says it isn’t is clearly crazy and possibly nefarious.
I am talking, of course, about Disney removing Muppets and Rivers of America.
