Are some parts of Chumash 'inappropriate' for children and better skipped than studied?

Is the Tzemach Tzedek's defense of not skipping anything just a 'one off' and not a fully sincere argument?

Analyzing a somewhat obscure 1902 polemical pamphlet issued by the gedolim of Russia and Lita (and endorsed by the Rebbe Rashab) sheds much-needed light on the context and history of this question, and provides insight into its application today.
