Never met a Catholic girl who wasn't on the pill.
One of my friends is a Buddhist girl who has in the past gone off on a tangent about how hormonal birth control disagrees with her interpretation of the sutras and throws the body askew of the Middle Way. (Not a hippie Buddhist girl. Her family is Japanese and Korean.)
Mumbo Jumbo is gibberish in any languange.
What on Earth are you talking about?
Incidentally, her argument isn't bad at all if one accepts the tenets of the Shingon school and takes the fact that the Womb Mandala is named what it is seriously (which, in a highly esoteric and mystical school like Shingon, quite a few people do).
