Rabbi Ysoscher Katz

Rabbi Ysoscher Katz is Yeshivat Chovevei Torah’s Chair of Talmud and former Head of its Center for Halakhic Studies. Rabbi Avi Weiss praises Katz as, "an awesome Talmid Chacham [Torah Scholar]."

While teacheing at YCT, he has espoused many troublesome and non-Orthodox views:

Claimed Jewish texts can be erased after labeling them racist and misogynist
“Chassidic and kabbalistic racism and misogyny is deeply problematic, and, of course, troubles me a lot, but the problem is intrinsic to Jewish texts in general, not just to mystical texts. It's true for the Tanach, Chazal, Rishonim and Achronim.  Texts are products of their times, strongly influenced by the contemporary social reality. As time goes by, we learn to adapt those texts to our new reality, excising or updating the troubling parts or reapplying them in new ways.”

Referred to commandments as an "insult" and "capricious and patriarcal"

“The Torah for Chassidim is there to teach us how to live life and serve God; the narrative quanarrative (the origin story) is  mere background music. The narration parts of the Torah are, therefore, not of much theological significance to them. They are a-historical.” 

Called the entire Torah "a-historical." He said (commenting on a Facebook Post):

Troubling Values
On Facebook, Katz criticized Moses while in the next post praised Leonard Nimoy as an artist.  (Nimoy created controversy in 2002 when he published a book of his artistic photographs called Shekinah which included pictures of naked women wearing Tefillin.)[1] 

“The Torah makes clear that [intercourse] between two men is prohibited, but I like to talk about the 50 shades of gay, in other words, there are many other things they can do that are not expressly prohibited.” (. )

(Contrary to Katz’s contention, the “other things” are in fact included under the prohibition of, you shall not come close to uncover nakedness. (Leviticus 18:6).  Also, it is prohibited to spill seed in vain (Code of Jewish Law EH Chapter 23), and the Torah forbids one to incite his evil inclination, as it says, do not stray after your hearts and after your eyes. (Numbers 15:39).  Coincidently, the official position of the Conservative movement is to prohibit the homosexual act itself, yet permit other intimate acts. (https://www.rabbinicalassembly.org/sites/default/files/public/halakhah/teshuvot/20052010/dorff_nevins_reisner_dignity.pdf. )

Katz has also wished that a commandment in the Torah would, "magically go away"
