A commenter on Reddit had this to say on a thread talking about the "Daddy I Do" documentary:
Whenever I hear the phrase "pledged her virginity to her father" it creeps me out, as though you're supposed to wait for Daddy to f*ck you. Though considering the likely psychology in place there, she probably is, in a way (her husband is just her new "daddy.")Perhaps the reason I don't jump to the incest accusations is because I know there is no intent in the movement for a father-daughter sexual relationship. But I do chuckle a bit at the line "her husband is just her new 'daddy'" because that's pretty close to the truth. In the more conservative communities, it's very clear that the headship over a woman is transferred from her father to her husband, the men in her life sharing similar roles in relation to her: namely, provider and protector.
Maybe I don't want to see it as creepy because I can see my old self falling into this belief system and lifestyle, or because I have friends who are still in it. Maybe I'm too focused on the relief I feel that I'm not living that life. Maybe I'm lying to myself and the creepiness is part of what keeps me fascinated by the subject. I acknowledge that the purity movement should seem a bit creepy to a normal person, but I don't feel that when I watch it and read about it. Maybe it's too real and not foreign enough to surprise me in that way.
