Why vampires in the Philippines are women? (How to kill em) 1

I wonder why fetus-eating vampires or manananggals  in Philippine myth are mostly women. They are portrayed as beautiful women that split their bodies in half , the lower and the upper part. Before the transformation...errr...rather, their mutilation, they go to banana patches to hide their lower extremities after which the upper body, propelled by bat wings, flies off in search of victims especially fetuses and defenseless children and once in a while adult women and men. It is difficult or almost impossible to kill manananggals in flight because, well, they are airborne and bamboo spears and bolos are useless against them unless they are caught off guard feeding which is almost impossible because they have bat sense of some sort that warn them of danger. Maybe a 50 caliber or 88 mm flak canon could kill them in the air ; but , then again, these are mythical creatures and they are way beyond science and technology.

This is the picture that caused a panic in Pozorrubio, Pangasinan. The folks there formed an anti manananggal-posse armed with bamboo spears, bolos and garlic. They roam around  at night to defend the village against the manananggal. One unlucky dog spotted under a truck, which I figured was a cross between an askal and a golden retriver hence it's size,  was thought to be a weredog and was almost killed by the men. The police had to intervene lest the suspicion turned on to people and who knows what could happen next. Irrational fear could make these people do irrational things like killing a neighbor suspected of being a mananggal or burning down the house of someone accused of being a shape-shifting aswang. Hmmm...I suggest the government educate rural villages about photoshop or photo editing to inform the folks that pictures can be manipulated.

Manananggals have one known weakness, their defenseless lower body. To kill them, it is necessary to find the lower body which according to folk myth are usually hidden in banana patches or in a forested area  (for urban manananggal, in a closet) well away from people. Once the lower part is found, it is killed by pouring holy water or putting salt, garlic, or much better would be to combine them all in a cocktail or soup of some sort (well, according to myth, anyone of these things could do the trick but one has to be on the side of caution, it is better to safe than sorry) pour it on the exposed innards and then hide and prepare to defend yourself because the manananggals would come back to check their lower body to find out why they're having phantom stomach ache.

Destroying the lower body of manananggals do not kill them instantly it only kills half of them, so, the other half, the torso with the arms and the head still survive for a period of time; the upper will eventually die either of hunger, infection, constipation, no bowel movement, full bladder....things that happen when one loses the small intestine, the urinary something and the anus. Once the lower body is destroyed,  best thing to do is to hide and wait for the upper to die naturally or to wait for sunlight to kill it. It would be futile to fight it out with raving-mad-angry manananggal who found out that her lower body was dead. Manananggals  are allergic to sunlight, like most night vermins and it naturally kills them.

Well, anyway...this getting too long. Haven't answered the question...another post.
