"The Christian bible teaches the opposite. To love everyone as much as we love ourselves. To love our enemies. To not judge others. Huge difference."
This is not entirely accurate. Christians have not jettisoned the Old Testament. The Old Testament message is strikingly different and is dangerous.
It is disingenuous for Christians to criticize the Koran while at the same time not rejecting the Old Testament. Judaism, Islam, and, Christianity have common roots. These three religions are all dangerous religions. All three teach falsehoods.
All religions are the creation of man. The new Testament is full of supernatural events. Modern Christians pick and choose which events they will accept and which they reject. They have in effect updated their religion for modern times. This is simply part of the continuum of man's creating and updating one religion after another. The harm they do is relative to their teachings. Some are nearly innocuous, but none completely so, and some very dangerous. And within each of these major religions sects develop which are more dangerous than the mainstream components.
A person such as yourself is moral not because of religion but despite it. We are one of the few eusocial species. Sociobiologists, see for example E.O. Wilson, recognize that our moral kindness toward members of our own tribe first, and then members of our own species, has evolved in us and is instinctual. Religious beliefs drummed into our heads from a young age can overcome our instinctual moral response to members of our own species. All three of the major religions originating in the Middle East, chiefly on Arabian Peninsula, teach that each is the true religion and that the others are false. They are all three pernicious in that they seek to cut off criticism of their teachings by one means or another and in this way have maintained their falsehoods for many centuries despite overwhelming evidence to the contrary.
In the U.S., where it is not possible to execute people for questioning religious teachings, the methods used are less draconian, but still quite effective. Today's ubiquitous "political correctness" has its origin in the reverence that these religions have traditionally demanded of their followers. Our instinctual, eusocial nature makes it unlikely we will call attention to ourselves by publicly doubting the teachings of our religious leaders.
