The 8:12 post? Well, I agree 100% with the first sentence:
there's no reason on earth why we should abandon the promotion of evidence and reason.   But it starts to go downhill a bit after that: Religion is very damaging on the whole, narrowing people's minds and giving them ... false certainties.

It certainly can do that, but it can also do the exact opposite. The bit I omitted was 'false hopes and' because that is actually the whole "Does God exist and what do you mean by God in the first place?" bit, which is far too much to take on here. And Dylan Thomas wrote "No man believes who cries not 'God is Not!'" Doubt, not certainty, is an important part of religion.

But let's look at narrowing of minds. I'd say the opposite personally: it continually challenges people to remember that they don't always get it right, that they don't know it all, that 'they see in a glass darkly'. Like any complex subject, it can take you to all sorts of places you never anticipated, like the greek philosophy I mentioned, or social anthropology, or how religion understanding has altered thoughout history. I consider that mind expanding, not narrowing. But it is a personal choice whether allow religion top expand or narrow your mind.

Science is also a rich subject, of course, so it can also narrow or broaden your mind, but the vast majority of people are not scientists and can live their lives happily enough without giving much thought to evolution, geology, quantum mechanics etc, etc, etc. I have a friend who is a keen amateur photographer and about every other day posts fantastically beautiful photos of sunsets on Facebook. I have little doubt she thinks of neither God nor the scientific causes of them. And while she certainly could, I see no reason why she should.

So I don't it is right to say religion itself causes narrow-mindedness. What does, though, is inculcating an attitude of "accept what you are told, don't think for yourself, we know what's good for you, and will tell you everything you need to know". And I fear that while the way religion is frequently taught makes it especially vulnerable to that, it is true for every subject, including science. What proportion of people have never questioned a scientific 'fact' they were taught at school, even when the science community passed it by decades ago? How many people still think the Rutherford atomic model is 'right'? Do people habitually question advertisements on whether the science and statistics claimed have any validity?   A few years ago we had a vote on the Alternative Voting system and one of the key objections raised again and again by the No lobby was that it was too hard to understand.   I think we need to look very hard at our education system if it is true the majority are incapable of understanding something like that.
