3) We are born something (for example Christians). We usually don't chose. We should decide as adults or even later if we want to support a religion and which religion.
Uhm, talking from a Danish PoV:
If you do not want to confirm your belief in the Christian God, you can refuse to do so at your confirmation at the age of ... 13 here.
Afterwards you can actually resign from being a member of the Christian church.
2) All churches have huge wealth, money and buildings. If they are that good why they don't use it to help people?
Not here, but there is something called "Emergency help of the Church" and "Christian help of people" which collect money to help people in both our country and everywhere else it is needed.
@1) Wars are usually for a stupid purpose anyway. No, I am not proud of the way crusaders and even the church and the believers have acted throughout history, because most of what has been done has been stupid and unnecessary, and actually against the bible.
Religion is what you make of it. And what you make of yourself. And what society make of you... It has been used by the government to control the masses...
Every religion and member is equal. There are no better or worst religion, all say almost the same things
And that is common moral and ethics, which should apply that all of human kind is equal, whatever they believe in.
An other thing many person say I am a Christian, have you ever asked yourself am I? Do you really follow Christ words? Or the reason you say that you are a Christian is because you are either brainwashed, because of peer pressure or fear of death, cause you have been "bad" or that your life ends there and after that there is absolutely nothing.
I asked myself that at my confirmation, and I could honestly answer yes when our priest asked me if I believed in the Christian faith.
I for most parts to follow the words of Christ, yes, but I find the old Testament to be made up of a lot of metaphors and strong rules that I cannot apply to my life, simply because they are what they are. The new testament is good enough.
Of course the Bible has been edited by humans, which makes it quite... Yeah, human.
Here in Denmark it is quite common to not be overly religious, and many does not really care if they are Christians or not. I have quite a few Atheist and Agnostic friends, and I admire them because they made the choice/came to that conclusion, because it shows that they actually have thought about it, and not only went with the easiest solution.
