Good post, and Theists often ask, "What is the harm done by religion?"<quoted text>
Their problem is simply RELIGION aka Organized Superstition.
Some are literally obsessed with it.
The Christian view that all intercourse outside marriage is immoral was based upon the view that all sexual intercourse, even within marriage, is regrettable.
A view of this sort, which goes against biological facts, can only be regarded by some people as a morbid aberration. The fact that it is embedded in Christian ethics has made Christianity throughout its whole history a force tending towards mental disorders and unwholesome views of life.
The Church had devastating impact upon society. As the Church assumed leadership, activity in the fields of medicine, technology, science, education, history, art and commerce all but collapsed.
Technology disappeared and the Church became the most cohesive power in Western society. The extensive aqueduct and plumbing systems vanished.
Orthodox Christians taught that all aspects of the flesh should be reviled and therefore discouraged washing as much as possible.
Toilets and indoor plumbing disappeared. Disease became commonplace as sanitation and hygiene deteriorated. For hundreds of years, towns and villages were decimated by epidemics.
Europe entered the Dark Ages.
Organised religion is violent, irrational, intolerant, allied to racism, tribalism, and bigotry, invested in ignorance and hostile to free inquiry, contemptuous of women and coercive toward children.
"I'm against religion because it teaches you to be satisfied with NOT understanding the world around you."
