Is it obligatory to obey one's parents regarding not marrying a Christian woman from the People of the Book, despite the son's love for her and his fear of his psychological state deteriorating if he does not marry her?

It is permissible to marry a chaste woman from the People of the Book, based on the verse: "And [lawful in marriage are] chaste women from among those who were given the Scripture before you" (Al-Ma'idah: 5). Parents do not have the right to compel their son to marry someone he does not love, but they do have the right to prevent him from marrying someone he does love; this is because obedience to them is obligatory, while his marriage to a specific person is not obligatory. What is obligatory takes precedence over what is not obligatory, unless there is a fear of harm. A woman suffering from anemia does not prevent marriage to her. If you wish to marry her, try to convince your parents. Otherwise, obedience to them is obligatory upon you, unless you fear harm. Abstaining from marrying her might be an act of filial piety towards your parents and a reason for you to be blessed with someone better than her. Marriages through social media platforms often end in failure. Despite the permissibility of marrying a woman from the People of the Book, it can be fraught with risks and harms, which is why some scholars disliked it.
