Understanding 「…などということは」


From a dictionary definition for なんて
([デジタル大辞泉](https://kotobank.jp/word/%E3%81%AA%E3%82%93%E3%81%A6-590615)):

> なんて の解説  
>  ［副助］《副助詞「など」に格助詞「と」の付いた「などと」の音変化》名詞、名詞に準じる語、活用語の終止形に付く。  
>  １ ある事物を例示して、それを軽んじたり、婉曲 (えんきょく) に言ったりする意を表す。なんか。 **…などということは。**
> 「手伝いなんてできるか」「本気にするなんてばかね」

**Question (for the bolded portion):** Why is this phrase encapsulated in a
いう? Suppose we said for example:

> りんごなど **という** ことは...

and then contrasted it with

> りんごなどは..

What's the difference in nuance between these two things? Is the first one
like putting something like dismissive airquotes around "apples":

> As for the so-called "apples and things"... (dismissive tone).

while the second one is just

> As for apples, etc (not as judgmental, and no element of hearsay of what
> society or other people have forced into the conversation)

?

In general, I feel like という frequently encapsulates things in Japanese, and I
never have a good grip as to why (unless it's the easy case, when someone is
literally being quoted).




The **「…などということは」** phrase is encapsulated in a **いう** because it means to
emphasize the things or anything before **as noun** , meaning **"... [some
subject or noun] which is"**.
