For those who support the total ban on women anywhere they would probably be happier if somehow one could make a wedding without the kallah too. There is some perversion of reality at play when you cant allow yourself to see a small girl modeling an outfit which is matching to a boys outfit and instead you would rather a headless mannequin. Because one wishes something were not seen doesnt mean it doesnt exist. It's fantasy, which is just as perverted and distorted as the thing it is supposedly intended to protect us from.
