Please, O liberals and accommodationists, get your heads around these few points before you start defending religion.
1. People have no automatic right to believe what they want.
In fact it's not always possible to choose what to believe. A close friend might be guilty of murder. I might not want to believe him capable of such an act but the evidence may force me to. I am duty bound to examine my beliefs and adapt them to fit what I can know about reality. More importantly, believing what you want doesn't necessarily affect just you. If you believe God ordered mankind to eat only halal slaughtered meat, your belief increases animal suffering. If you believe your daughter will please God more without a clitoris or labia, your belief ruins her life. Beliefs affect actions, and are therefore not immune from criticism.
2. Religion is not all about being nice to people.
It is almost universally assumed that real religion is something good and virtuous. Starting from that assumption, it follows that no bad act can be inspired by religion. Since no one can deny that bad acts happen, and that some of those who do bad things claim to be motivated to do so by their religion, it follows that bad people must have misunderstood their religion or must be acting on a perverted version of it. All this special pleading falls away, at a stroke, once we drop the initial false assumption of niceness.
3. Religion instils tribalism from an early age.
Children are taught, by religious parents and educators, that they belong to an in-group, while those of other religions form an out-group. God favours the in-group over all others. There is nothing nice about such an idea.
4. Religion is not race, and is not hereditary.
Religion is often confused with race, because, in an overwhelmingly large proportion of cases, a person's religion turns out to be the same as that of their parents. But that is not the same as saying that religion is unalterably inherited, like DNA. A child taken at birth from its natural parents, for whatever reason, would not automatically find itself believing the same things its parents believed. Children become religious through indoctrination, not through reproduction.
5. Those who claim to be religious often fail to evaluate the ethics of their own words and actions.
It is as though people think, "I am religious, and therefore a nice person. Consequently I do not need to monitor what I say or do, because the very fact that I am a religious person means that what I say and do must be good." They then go on to spout dreadful racism (a case in point is a British teacher, and self-confessed Christian, whom I heard to say that he certainly didn't want an Indian person teaching his daughter) or commit the most vile acts of murder and sadism (check out the news virtually any week).
6. The moderate religious majority creates the background against which religiously inspired violence can be justified in the minds of those who commit it.
Who claims that the Aztecs, tearing out the beating heart of a fresh victim each day to propitiate their preferred deity, were following an extremist perversion of their religion? Yet, after every case of religiously inspired violence reported in the media, liberals and accommodationists repeat their chorused trope that atrocities have nothing to do with religion. Thus, the root cause of the problem remains unaddressed, and the bombings, shootings and beheadings are not only authorised but guaranteed. Instead, we need to look at education, and aim for a state of affairs whereby any belief not founded on reliable evidence is open to robust questioning and evaluation. Nothing need be sacred. If you think that is impossible, look at religions of the past that no-one follows any more. The sun god Ra held sway over a large part of the civilized world for thousands of years - longer than Christianity - but who worships him now? Today's religions will eventually go the same way. Proper education could have an impact within a generation.
