A few questions

Hello Rabbi, thank you for the response that you always respond and answer… it's not obvious. I wanted to ask a few questions:

1. Are girls allowed to enlist and/or go to national service?

2. Do you think we should study morality? Should we study it every day?

3. Is it permissible to divide the seven blessings at the wedding between several people?

4. When reading the Haftarah. Should one read with the reader in a whisper?

5. A person who owns a bookstore. Is he allowed to sell books that are halachically forbidden to read?

6. Does the value of equality adopted by postmodernism contradict the Torah and Judaism?

7. Regarding the verse: “It is not in the heavens,” the Sages demanded: It will not be found among the scribes and merchants; I asked, and are there also some who are scribes and merchants and among whom Torah is found?

8. A person who saw a prohibited video (meaning the content in it is prohibited. For example: explicit), and liked it. Did he make the like prohibited by holding the hands of the perpetrators of the offense (I am not referring in my question to the prohibition of viewing the video)?

9. Is gambling allowed?

10. Is there an obligation to recite Kaddish? If so, is it for all its parts?

Thank you very much in advance for your consideration…
