Sex was always surrounded by taboos, and I don't see it necessarily as a manifestation of evil. I think that sexuality is first and foremost the way that God chooses for us to be here on earth, to enjoy this energy of love in the physical plane.
Man is always something worse or something better than an animal; and a mere argument from animal perfection never touches him at all. Thus, in sex no animal is either chivalrous or obscene. And thus no animal invented anything so bad as drunkeness - or so good as drink.
I would ask every man and every woman who's had the blessing of having children, 'Would you deny your son or your daughter the ecstasy of finding someone to love?' To love someone takes a lot of courage. So how much more is one challenged when the love is of the same sex and the laws say, 'I forbid you from loving this person'?
Scientists can routinely predict a solar eclipse, to the minute, a millennium in advance. You can go to the witch doctor to lift the spell that causes your pernicious anaemia, or you can take Vitamin B12. If you want to save your child from polio, you can pray or you can inoculate. If you're interested in the sex of your unborn child, you can consult plumb-bob danglers all you want . . . but they'll be right, on average, only one time in two. If you want real accuracy . . . try amniocentesis and sonograms. Try science.
