Viviane this thread is an example of a poster asking why some atheists seem to want to convert people to their way of thinking. I grant that the OP is not very clear but the question regarding conversion to atheism is.
Some posters reply with understanding that the topic is asking why some atheists seem to devote so much time to persuading people to move away from a belief in God while other posters seem merely to want to argue that you cannot convert to atheism because it is a lack of belief.
The latter are not engaging with the OP regarding why try and convert others to atheism. In other words why not live and let live, why care what others believe if they are not hurting anyone. They are being pedantic.
This is what I was referring to and I have come across it many times. Fortunately not very often these days as we do not have the endless atheists versus believers threads that were prevalent a few years ago. You only arrived a year ago so I suppose it is understandable that you haven't seen them. I take it this is why you asked for an example, I hope you weren't accusing me of lying.
