The idea that God is a "he" is not a Jewish invention. In Hebrew the only reason a male pronoun for God is used is that there is no neuter pronoun available in Hebrew. This has been changed in the English language now and even altered the Western world in the process.
At times the term "he" might still be used in English by a few Jews, but these days it has become less and less. The real reason? In Judaism it is forbidden to attribute a gender to God. If you haven't noticed yet, I almost never use any pronoun for God. Judaism was at the forefront of the inclusive language movement in English-speaking countries at the end of the 20th century where things from Bible translations to Siddurs and the Haggadah were revised to remove all gender references to God that had actually been caused in English by Christians and their formal-equivalence translations of Scripture.
Also neither Judaism nor the original historical Christian religions taught that the Bible was required for religion. Christianity was without a Bible until the heresy of Marcion of Sinope, and that canon was developed mainly in response to his heretical ideas that began spreading. Judaism did not originally have a canon as the concept is a Gentile one. The "official" text of Judaism became the Masoretic text developed between the 6th and 8th centuries CE. The New Testament's canon was not closed until the 4th century CE.
Thus the idea that the Scriptures are even a requisite for our religion let alone morality cannot be substantiated as we have done without the Bible for centuries, for most of our religion's history. The Second Temple was far gone for at least six hundred years before the Masoretes began their work and it would almost four hundred years after Christ that Eusebius and Athanasius would finalize the New Testament. The Bible is only the center of religious revelation in religions like the Jehovah's Witnesses promote.
Far more can be said to reply to Heaven's statements which seem molded due to exposure to the Watchtower and other anti-Jewish teachings. Judaism even helped introduced the inclusive-language movement over the last 50 years that changed such everyday terms such as "fireman" to "fire fighter" and "mailman" to "mail carrier" due to Judaism's need to alter English Jewish Bible translations to better resemble the original Hebrew. So yes, there is even more in response to those common mistakes about 'killing babies' and 'promoting slavery' that Heaven obviously also missed while English, Heaven's own language, was altered due to a movement we Jews helped inititate. If a person missed that and failed to bother how that happened to their own language, it is no wonder why they stick to such fraudulent ideas about Jewish religion.
The problem with these arguments is that they have their root in uneducated and often anti-Jewish stereotypes that some never bother to investigate but do not mind to perpetuate. In the end consider, how would any of these things change the Jewish view that I previously wrote of in my former post? If the Tanakh is 'so filled' with these horrible ideas, where did Judaism get these others? The problem is not Judaism but the failure of people to be logical in their assessments by too often defining Judaism by Christian and anti-Judaism lenses.
Regardless of what you or anyone wishes to mistakenly believe about Judaism, the fact remains that Judaism does not teach that morality is an exclusive facet of religion, belief in God, or Scripture.
