Life is a sexually transmitted disease and the mortality rate is one hundred percent. R. D. Laing 
Sexually Transmitted Disease or STD are diseases that are spread through sexual activity. Some sexually transmitted diseases, notably AIDS are spread through different ways as well. Even when these diseases are transmitted sexually inocent people are vulnerable since the faithful husband or wife of someone with a Sexually Transmitted Disease is at risk of infection.
Cruel Christian Conservatives see sexually transmitted diseases as a punishment from God and fight against public health measures to prevent those diseases. Former Pope Benedict XVI over several years discouraged comdom use even to prevent infection, see A problem with AIDS. Later Benny changed his position and accepted condoms when used to prevent disease, see Qualification.
