Religion was developed for the purpose of controlling large masses of people.
1. Conspiracy theory
2. In many cases, for good reason - those who wish to rape and murder unabated need to be controlled, as they lack the morality and self-restraint to so out of goodness, rather than out of force.
You would be more justified in saying that about virtually all "mass media and propaganda itself", whether for "religious, political, or advertising reasons", which.has been around since the days of ancient Rome, if not before.
Those who read books instead of consuming primarily propaganda are generally the better off for it, and the less dumbed down.
Religion is also one of the primary reasons there is pure evil in the world
Science more or less debunks this, such as fields like evolutionary psychology which reveal that the proclivities to engage in illegal or immoral behaviors such as murder and rape are genetic.
Which incidentally coincides with much folk wisdom and teachings of world religions, which compare those unchecked "impulses" within humans to the behaviors of feral beasts, as well as "secular" systems and treatises on civilization as well, such as John Stuart Mill's assertion that "it is better to be a man dissatisfied, than a pig satisfied". As well as the basis of legal concepts such as intentions, premeditation, crimes of "passion" and what not, which distinguishes between notions such as premeditation and intent, or commuting a crime while "in the heat of the moment".
Most religious people are the most intolerable and judgmental in society.
1. That, in itself is a judgment and lack of toleration.
2. Yes, religious people who believe in religious morals, such as that raping, murdering, abusing children, and so forth tend to be judgmental about those things, as opposed to those atheistic who aren't, and that's of course a good thing.
Let people live the lives they choose and focus on our own lives and what makes us happy.
As an absolute rule, or assertion of what inherently is?
No thanks. Not all "happiness" is created equal - a rapist believes "happiness" comes from raping women, a pedophile from raping children, their atheistic, "life is meaningless" world view substantiating that.
But of course, due to our society and our law being founded on religious morality, such as the Golden Rule, we thankfully do not put the so-called 'happiness' of rapist or pedophile on par with the "happiness" of a moral individual. And for good reason.
This should be exercised by following the existing perimeters of our laws, e.g. no child molesting, no killing............
Those are of course religious morality, such as the Golden Rule our Common Law having evolved out of older systems of law and religion, such as Exodus, and its acknowledgment of concepts such as respect for other people, their families, their property, and so forth.
Wheras, of course, raping, murdering, child molesting, are just the mere practice of nihilistic atheism, and those who believe life is meaningless, as per evil atheists such as the Marquis de Sade, or the morality of cults such as LeVeyan Satanism, which doesn't in theory, to my knowledge prohibit any of these things or condemn them as immoral.
Thankfully, as our law is founded on the religious principles of respect for people, their property, their family, and so forth, even if an nihilistic atheist claims his happiness is depend on these things, the law will force religion on him whether he likes it or not, and for good measure.
