I came across the following sentence:

> 僕が何を怖がるっていうんだ？

which was translated as "What am I supposed to be frightened of?"

I know that the first part means "what am I afraid of?"

I just can't see how adding that っていうんだ could change the meaning in that way.

I'm assuming that it's the same as というんだ but I still can't figure out how it
affects the meaning of the sentence.

Could it be a mistranslation on the author's part?

question
translation meaning rhetorical-questions
Ｗhat does っていうんだ mean?
You are right on assuming っていうんだ is the same as というんだ.

というんだ is basically saying somebody is saying the part before と in the
questioning form. That idea expressed before と is somebody else's, so isn't it
a good idea to question it with "be supposed to"? (Maybe it can be a self
questioning, but I have no idea without the context.)

It's literally like "What are/is they/he/she/you saying I'm (going to) afraid
of?"

answer
> 僕が何を怖がる **っていうんだ？**

It's a rhetorical question (修辞疑問文/反語表現). It's not really a normal _question_
that asks for an answer/reply. It means/implies "What would I be afraid of? --
No, I would be afraid of nothing!"

Examples:

>   * 誰が知っているというのか。  
>  "Who knows? (Nobody knows.)"
>   * どうすれば忘れられるというのか。  
>  "How could I forget? (I could never forget.)"
>   * それがどうしたっていうんだ。*  
>  "What would it matter? (It doesn't matter!)"
>   * やつらが金以外のなにを欲しがるというんだ？*  
>  "What do they care for but money? (They only care for money!)"
>

The latter two examples are taken from
