In the movie, this is a reference to the racist townspeople in the "Western". It's poking fun at the Westerns that romanticized allegedly good and pure settlers (colonizers) and to sympathoze with them. You weren't supposed to think of them as, in Wilder's terms, "morons".

Parent was just trying to call people morons. It's not a clever reference, I got it. But those people are, specifically, Muslims so put off by the genocide of Palestinians that they'd vote against the administration supporting that grmocide. I would say their political acumen is more developed than the genocidal sheepdogging that we see in this thread, people that can't even say the word genocide trying to imply they're the adults in the room. At least they can understand basic leverage and independent action.

But I was making note that the "morons" reference in Blazing Saddles is about settler-colonists whereas the people parent wanted to call morons are literally people that are reacting against settler colonists and their supporters. I think that is an oversight that can only be made through chauvinism, personally. The person wants to feel better than those moved by genocide, they want it to be as narrow as "those people are stupid". They can't contend with the content.
