Sorry atheists, but we need the Christians.ST
I'll disclaim this at the start that I don't follow any of the world religions, do not believe there is a God, but have no evidence to prove one does not exist.
I want to present an alternative view of the history of the world, because the Christians are getting a hell of a lot of stick recently, and I think that's a bad thing for the world.
Survivorship bias: Pagan religions didn't die out because their Civilisations died out, their civilisations died out because their religions were suboptimal at keeping them alive.
Taking a look at the religions that have survived today, and in no particular preference, cherry picking a few of their values, when taking the religion to a fairly strict level.
Oppression of women
Unable to eat pork/shellfish
Dont murder anyone (unless they don't do what your religion says they should do),
Anyone can convert into it,
If you leave it (apostasy) you die.
You should convert people to it by spreading the word.
Roasting in hell for eternity if you don't join.
Cheap to do.
Being rich is against God's will.
Religion passes through the mother
I'll go through each of these points as to why they're almost a requirement of a surviving religion.
Oppression of women, banning contraception and banning homosexuality: If I wanted to build an army, I need numbers. These 3 are easily the best way of churning out numbers with no questions asked (God said so, remember?).
Unable to eat pork/shellfish: Shelf life of shellfish is bugger all, and pork was, until relatively recently riddled with tapeworm. This will cause illness and death in a community. Ban it = better health.
Don't kill or steal. To operate a more efficient organisation, you need it enshrined in afterlife law that not only do I not want you doing that, but God doesnt either.
Acquiring wealth is also a nono. You are also far less able to mount any form of uprising or insurrection without funding. Keep people poor and you keep them in line, and also in dire need of a God. Correlation between poverty and religion is not coincidental.
One God: Simpler and also means you dont waste time praying to many Gods. You can sort out your religious duties in one place for a few hours a week.
Belief goes through the mother: No doubt as to who the mother is. Guaranteed child of the faith.
Now the main ones. Don't convert to my religion, I have to kill you. Convert and you live, and you upgrade your afterlife, significantly. That's not a hard choice, especially given the theatrical deaths the hardliners took when they refused to abandon their faith. If you leave, I kill you.
Cheap: Not a huge burden on your resources to sustain. Case in point in Malaysia, people have converted to Christianity recently as the cost of sacrifices and lengthy rituals to many Gods,
So how does this all fit together? These religions have created a culture which is more effective than other cultures in creating numerous devoted zealots who will die for their cause. These cultures, combined with human nature will spread and overrun anything that stands in their way.
So why do we need Christianity? It's the least restrictive of the surviving religions, and we need something to resist the conversion to other belief systems. It's readily attacked because it doesnt fight back unpleasantly. This incessant assault by the atheists is weakening its position. It's the lesser of the 2 evils that we face, and we could do with a few people on our side that will die to defend the culture. Not only that but when we do find an alien civilisation, we'd best hope we outnumber it, outgun it or some combination of the two. Looking at the progress of the Christian nations compared to the others indicates that it is better suited to ensuring the survival of the human race than others.
Hope this doesnt start a ****storm, probably will though.
