Understanding っていうのも


The kids have decided that they don't like their new teacher:

> A.「ああいうタイプは気取ってやがるに決まってるんだ」  
>  It's certain that this kind of person acts like a snob  
>  B.「決まってる **っていうのも** 強引だけどたいていそうだよね」  
>  The thing you call certain is just pushiness, but it's usually like you
> say.

My translation doesn't quite make sense. I assume the meaning is "What you see
as snobbishness, I see as pushiness". But if so, why is it not 気取ってやがるっていうのも.
Does っていうのも refer to the thing described as 決まってる or to the phrase 決まってる
itself? Or have I completely misunderstood?

Also what nuance does っていうのも give rather than っていうのは.




That の is a plain nominalizer, and って is a colloquial variant of the quotative
particle と. 決まっているって言うの refers to the action of saying 決まっている. 強引 is a na-
adjective here.

> Saying 決まっている (=definitely) is too assertive / too much, but it's usually
> like you say.
