We shouldn't ban religion, but we also shouldn't build churches. We shouldn't burn the books,nor call them perfect. I am an atheist. Have been for 7-8 years now. It might not seem like much, but i am 20. After losing friends because of religious debates, i realised that the best policy is "Live and let live". There are plenty of people that bind religion and science and we shouldn't disregard them in any way.
Take this example: let's say that Asgardia will take off like crazy, and we will get the chance to go to space. All of us. On ship the size of a city. Now, the biggest problem we will have there will be each other. We have to get along. And on that ship, let's say it is a sunday. Day off. Well, i want to sleep in. But if i have a church nearby, banging the bell, cant really do that. But also, can't go to the church and say " Don't use the bells!"
The only ideea i can come up with is this. We shouldn't ban religion, bit we should ban the topic of religion. I am pretty sure that a true believer dosent need a church to pray in or a need to cenvert anyone. So just ban the subject. What you do in your home is your business, but when you are in the community, you don't talk about that. Like sex, pretty much. We should aim to keep it private. If the parents want to teach their kids about God, they can do that. But if they don't, they can also do that.
We can't expect to be the same, because we are not. So subjects that we see that on Earth are bringing hate and crime and war between people should be banned in the comunity.
Another example here is history. I have seen first hand a French Guard at the Luvre refusing to help a german speaking lady. Might have been an isolated incident, but if we are to form something better than we have here, all the hate and mistrust ("i don't trust him, he is whatever and i know they can't be trusted") must go away.
This is hard, we are influenced a lot by our history, but to be able to work together with anyone, we must lose that.
We are not French or British or Russian or Chinese or Madagascar-ens. We are Asgardians and to that end we must be willing to make sacrifices, must be ready to leave who we were for who we will be.
