Although this statement was made in perhaps a very disrespectful manner, it makes sense why someone in the yeshivishe velt would say something to that effect, albeit with different words. In general, with regard to sticking to the mesorah and not saying more literal explanations in almost every topic in chumash, that is the order, with Rashi always quoting gemaras and midrashim etc., Ibn Ezra generally saying his own pshat with sometimes open disregard for midrashim, and Ramban and Rashbam somewhere in between. There is a very interesting Rashbam in the beginning of Vayeishev that is relevant, ?”?.
Helpful – Funny you should say that, in fact Conservative and Reform would probably use the same tone but they would say exactly the opposite.
