“It’s not Shabbesdik” is the last resort of someone who has no argument.
No, Rebbetzin, we don’t all know these things intuitively. They are not universal truths, they are your personal preferences and prejudices which other people don’t share. There are more ways to celebrate Shabbos than are dreamed of in your constrained vision. More ways to dress, more ways to eat, and more ways to spend the day. Not everyone has to be the same.
