My experience reading Jhagi Bhai is that she cares a great deal more about her opinion being correct than being popular. So I do not think she is virtue signaling because that, to me, implies people who make overt statements of self-guilt in their pursuit of internet love.
I read her piece as an inquiry. As if she was saying “tell me how this parallel is wrong”. So I did. I am still left wondering how her Yiddish is so good.
