I will preface this question by stating that I do not subscribe, nor ever have subscribed, to the misogynist beliefs in the bible. Women are not subordinate to men. Period.
Scenario: A woman who is married decides that she wants to become a baptised Jehovah's Witness. Her husband says no. She says no more but goes ahead and gets baptised anyway without her husband's knowledge. Is her action contrary to her husband's headship? Is this ok according to Watchtower doctrine and practice?
