No, however I may have sown a seed a few years back. My job as a trainer takes me all over the UK and as far as Australia and enables me to train people from all religions, backgrounds etc. I was training a site in London with delegates from a mainly muslim, hindu background. We were having a chat at lunchtime and the topic got onto religon (nothing extreme. This is England after all). They asked what religion I was and I said I didn't have one. I just said that I believe in being nice to people and leading a good life. You could suddenly see their neurons start to fire and a bit of logic creeping in.

Yes and I felt a bit guilty afterwards. It was an African guy from Nigeria I think. He told me his father had type 2 diabetes so I piped up oh in that case you must have had white ancestory. Well this got us on to talking about Neanderthals and how it was they who carried the T2D gene and as there were none in Africa, its likely he had a European ancestor, so we talked about genes, hereditory and evolution. I remember him looking at me and saying, 'this means there isn't a god'. He looked so crestfallen I felt dreadful...hope he moved on.

No....because I don't waste intelligent time trying to convert a person; I believe the conversion must be self-made to be meaningful. Without reasoning it would be the replacement of one belief by another.;

Yes. A work colleague who I travelled a lot with. He was very guilt ridden because of his religion. We used to discuss it frequently. I never forced my views on him but just explained why I thought the way I did. When he mentioned things, I'd just ask him why he thought that. It was hearing his own answers that made him doubt his beliefs. Eventually he realised that they didnt make sense and now openly admits that he no longer believes. He is a much happier guy now. Guilt free. We are still good friends and still talk a lot about religion.

Yeah, quite a few.

I have never overtly or actively tried to deconvert a theist. I do know some who've discussed their doubts with me, I told them my thoughts and eventually they left religion on their own
