Ines I think your approach even not totally wrong, in fact some girls here started to wear the belt as protection, I think the conceptualism of the girls as victims is not the main motivation under modern belting of the girls.
I think, that in most cases, parents think in "preservation" before than in "protection". They, in general, are not in panic about rapes, more well they are fear of girls bad steps before marrying.
Thanks to your post you have highlighted a subtle distinction but of capital importance.
Indeed, according to you, the main motivation of parents to wear the belt to girls would be to preserve their virginity rather than protect them against possible rape.
So if we push the argument a little further, it means that these same parents would feel less affected (or less distressed) if their daughter would lose her virginity against her acceptation (in case of rape) than if their daughter had lost his virginity by making love to a boy with all his heart.
And here I must admit that I am deeply revolted that some parents can think that way.
Indeed, in such a case, it is clear that it is the ego (or pride) of parents who prevails over the emotional security of their daughter.
It simply shows a deep selfishness on their part and I will never be convinced that such parents can act out of sincere love for their daughter.
In fact, it is not their daughter that protects but their own pride (their own vainness) and it shocked me deeply.
I consider that the primary mission of a parent is to protect his daughter from any external physical and psychological danger without affecting her consent or sexual fulfillment.
For my part that parents who sincerely love their daughters must put their physical and emotional safety above the honor or reputation of their daughter.
I think a good family man claiming sincerely loved his daughter, should invest in this kind of equipment:
I honestly think it's a great invention to protect the girl against potential abusers while leaving her full of sexual freedom.
If for example the girl is a bit drunk during an alcoholic evening she can not be sexually abused against her will.
It's my educational philosophy.
