This is something I've wondered about for ages, myself.
Scientifically, it has been known for more than a full century that human beings, who intimately share infected bodily secretions, spread disease among themselves and all others with whom they later come into intimate contact, and even to their innocent offspring. Lifelong disease is not something for which sane human beings strive. Yet it is the absolutely predictable -- scientifically! -- result of this "sexual liberation" social construct. "Sexual liberation" has produced whole generations of smart people, who wouldn't share a glass of water with a stranger for fear of contracting a communicable disease, but will willingly copulate with the same stranger in scientifically deluded fashion.It just amazes me that the same kids that obsessively use the anti-bacterial gels will be, many times, the same ones that engage in intimate activities with strangers.
