Dor, it s mindless if you did not ask him. It is certainly mindless regarding non-Torah matters. The Gemara mentions many instances in which people disagreed with their rabbanim (הא דתיה הא רביה). The Rema says (YD 242:3).
הגה: אבל מותר לחלוק עליו באיזה פסק או הוראה אם יש לו ראיות והוכחות לדבריו שהדין עמו. (פסקי מהרא”י סי’ רל”ח):
Rav Soloveichik’s rav was his father. However, when his father opposed his choice of wife he wrote him a very respectful letter proving that he did not have to listen. Rav Moshe Soloveichik told his friends that his son was right.
Stuart, on the contrary, Rav Lichtenstein wrote a whole article AGAINST the idea of daat Torah. You can google “If There Is No “Da’at, How Can We Have Leadership?” BTW, what did you mean by “Father from chassidish background, mother from background”? Does she have an anonymous background?
