“2] If the only answer is
moche , moche , moche
and nothing substantial ….. that is also shtikah …….”
In Choshen Mishpat, this is absolutely false.
I don’t know if this rule applies at all in Torah Debates. Maybe I just can’t figure out what you want. Maybe we have different interests in this discussion. You can have yours, I’ll keep mine, and they will keep theirs. There is no contradiction if we all have different opinions.
