Is reading Elie Wiesel and Leon Uris an issur de-oraisa?

In The Taryag Mitzvos by R. Aharon Yisrael Kahan Mitzvah, a work based on the Sefer Hachinuch it says in Mitzvah 387 based on Num. 15:39, וְלֹא-תָתוּרוּ אַחֲרֵי לְבַבְכֶם, וְאַחֲרֵי עֵינֵיכֶם, אֲשֶׁר-אַתֶּם זֹנִים, אַחֲרֵיהֶם

It is forbidden for a Jew to introduce into his mind, through reading or otherwise, any ideas that contradict the true Torah values. This includes books, newspapers, magazines, movies, etc. Although the quality of acceptable reading material available might be insufficient to satisfy our knowledge-hungry youth, this does not excusse the reading of anti-Torah literature, just as one may not eat pork, even though no kosher meat may be available. Any Torah-true Jew must forsake the works of the following authors: Ash, Bialik, Buber, Singer, Weisel and Leon Uris, to mention a few. The distorted attitudes and opinions of these shallow minded, non-Torah-true individuals are contradicting to our forefather's [sic] sacred teachings and traditions, and their venomous writing tend to instill anti-Torah values into the minds of their readers, chas v'shalom.

Wow, this is the first time I have ever heard Elie Wiesel's writing called "venomous". Leon Uris?
