Sometimes a good rant has to be acknowledged.
But I don't find myself in full agreement with the quote that you approvingly quoted, wherein it was stated:
Well said. The sad thing is that it doesn't matter what you say; Religious people are blissful in their ignorance. I think most of them realise they're wrong but can't let go, which is the most pathetic thing I guess. The irony is that the most widespread religions, Islam and Christianity, are actually probably the worst. I think the world would be a much better place without the kind of people who follow the mainstream religions. They just hold society back.
Of the small sample of "religious people" on Earth that I have ever gotten to know somewhat well -- a few thousand, I suppose -- out of the 5 billion total or so that I suspect can be described as "religious people", most of them truly believe in the basic architecture of their religions and are very nice people and make the world a pretty decent place to live.
We focus a lot of our attention on bad actors -- Catholic priests who rape little boys, imams who issue fatwas that lead to death and destruction, fundamentalist Christians who take your cash and scare the crap out of you -- but the worshippers are generally pretty decent people. They work, raise children, coach youth basketball teams, fundraise for local charities, pay taxes, contribute to their communities and so on. These are good things.
I imagine what really gets under our skin, we secularists (on the basis of the currently known evidence, we all came from a Big Bang and all corporeal matter will all end eventually up as cosmic dust) just can't stand the sight of people praying to a god that we know very likely does not exist and submitting to an artificial authority in the name of that god. But I'm not yet convinced that on the the weight of the evidence that religion has done more harm than good. We know about the harm, but we should not deny the good.
Religious people may be blissful in their ignorance, but even ignorance truly can be bliss and bring bliss to others. And for many, the horror of waking up to the abyss may be too much for them to bear. For most of us, as Lucretius rightly suspected, the realization that there is no afterlife and that we are just a composition of particles temporarily formed into an organic mass, could unleash passions that are even more destructive than the destruction caused by the imposition of religious dogma. For Lucretius himself, this realization was liberating, but very few of us can think like Lucretius.
But even an extraordinary thinker like Lucretius believed in the existence of gods of some kind and even his mind led to strange conclusions about the physical world. Secularists have to be careful not to let their own passion, their anti-religious sentiment, take their mind too far astray from day to day observations about the benefits of religion, not just its vices.
