I also think that a large part of the opposition to a belief in God is because of the conduct of so many who claim to be Christians. It’s like anything their provokes strong feelings, there is usually a minority who shout the loudest but whose views are more likely to drive people away than to draw them in, and the people who just believe and just want to go about their lives don’t want to be seen to be a part of that and therefore the only view that is seen is the judgemental one.
We have the same with e.g. radical feminism, climate change, etc.
I went to a school abroad which was owned by the church and who very much upheld the view of fire and brimstone. I had friends who told me if i didn’t believe I would be going to Hell. After the challenger exploded a teacher said that because there was a teacher on board God obviously believed this was wrong and that was why it happened.
I went to church with My BF once and afterwards the congrigation were asked to stay for a talk about the finances of the church, and this was a large church, certainly not short on money. And the pastor stood there and said: “we shouldn’t judge those who give of what they have. The ones we should be judging (his exact words) are the ones who give but could give more.”
Since then I have got together with my DP who is a Christian but we don’t talk about it. However, friends of his have told him that as I am not Christian he shouldn’t be with me, that if he chooses to be with me he will forego the ever lasting life. In my life I have never been judged quite as much as by people claiming to be Christians.
And the sad fact is that many actual Christians recognise this and the fact that so many who claim to be Christian are so judgemental and quick to stab one another in the back. yet nobody stands up to this. And therefore it is the judgemental attitude, the wanting to rule by fear, that is the overriding message given out by many Christians, and the truth is that you are never going to convince people that that is something good to believe in.
