Trouble is Trade.
Religion has always taken sides and sponsored wars.
Simply because a religious person is no different to a non-religious person.
I'm really not sure how your post adds to anything. Christians TOTALLY agree that the religious and the non-religious are no different.
We are all born sinners. We all deserve to go to Hell. We have all rejected God as the king and master of the universe. No one deserves heaven.
Yet having said that - since our human nature is corrupted, and we have no method of changing that nature, we are able to acknowledge that fact. The rest of the world either ignores the fact that every person is sinful, doesn't care, or denies it.
Christians however, despite the fact that we all have fallen into the last three categories have by the grace of God, been enlightened by his Holy Spirit to recognise that we are sinners and worthy of Hell. This doesn't mean that suddenly we have been given some kind of clue to become Christians. Yet it does have the impact or effect of causing us to humbly reflect upon why this is the case.
In the NT, when people recognised that they were sinners, they cried out to the Apostles, what must we do to be saved? The response was - "believe in the Lord Jesus Christ and you will be saved." The response wasn't to give up all your money to your favourite charity. It wasn't go and do good work. It wasn't to get wet with water. It wasn't to be the right colour or the right nationality. It wasn't to become the right gender. Or follow all these rules. Nope. It was none of these things - because all of those things mean you have somehow found a clue. A right path to heaven. A magical superstitious method.
In Christian circles, there is a debate about whether belief in Jesus is a condition or not to become saved. This is generally but not always referred to as the Arminian Calvinistic distinction. Sometimes it is referred to as the Augustine Pelagius distinction. In non-religious philosophical terms, it is referred to as the deterministic free will distinction. I prefer to call it the Reformed non-Reformed distinction.
Basically, it comes down to whether God saves us or whether humans have some part in their destiny. The Arminian or Free-will person would suggest that humans can be saved if they believe in Jesus as a condition prior to salvation. Calvinists suggest that belief or faith is a gift from God that reflects that you have already been saved. Hence the former would see the belief aspect as a condition to be saved. The latter see belief as a fruit of salvation. I prefer the latter view since God doesn't play favourites. Whereas I would hold to the view that the former view - suggests that humanity plays some part in their salvation.
Hence, why I think the so-called Christian Nazis don't understand the concept of the gospel. I take the view that the Bible teaches that there is nothing about humanity that God looks down on and says - they deserve to live. This is the only manner in which everyone can be equal. If there is something about someone, then God MUST save people and that wrongly puts an obligation on God. Yet, in Christ, people can be equal.
So in response to your remarks, yes, religion takes sides. This is human nature and why non-religious worldviews also take sides. There is no such thing as true neutrality. Yes, religious people are no different to non-religious people as a general rule as well. Religion of course as a general rule is an ideology that subscribes to the view that the characteristics of a person - make them valid and worthy. Hence, I put non-religious views into that category, i.e. atheism. Christianity on the other hand, although it is technically a religion is also non-religion in that it says - there is nothing you can do to appease God. That's why Christians often say it is not a religion but a way of life. I am not a fan of that view. Yet, I understand where they are coming from. It is only Christianity, where God says - you can't do it, so I will do it for you. For me that makes it unique and preferable. And also reflects reality. Humanity has shown for the past several thousand years they don't have a clue.
