Atheism is a more adult world view than theism. Adults, we would hope, would talk to each other with reason and respect; of course in the real world it rarely works like that. However, in the real world an atheist
talking to a theist is almost always similar to an adult talking to a
child. Anyone who has raised a child knows that you have to use much
more than just reason to get through to them. If it is a child you care
about, you are going to try anything you can to help put that child on
the path to becoming a good adult.
It might seem that the analogy of an adult talking to a child is condescending, but it is not. An atheist's understanding of the nature of consciousness is more evolved than that of the theist. Because of this, atheists have a certain obligation to try and help others move towards intellectual maturity. The question is, how do we proceed? Rational arguments have been out there for years, some for centuries, and they totally support atheism. Obviously rational discussion alone is not enough to convince our descendants to adopt the scientific method over blind faith, or even to compel my son to wash his face. So what other tools to we have in our tool box, and how should we best utilize them? Shame, guilt, ridicule, rule of law, and military force are a few examples that come to mind.
Children are not brainwashed by religion. They are “brain soiled” or polluted by it. It is a poison that hinders critical thinking and stifles their innate curiosity with the “goddidit” answer to everything. It can take a long time to clean the brain after this soiling and some – like some recent zealots on this site - never break free of it. They do not see that they are deluded but think that Atheists are. They think that their faith is a personal revelation from God to them that they have discovered it by themselves. It never occurs to them to analyze where they got it from. It has become normalised behaviour for them. Fundamentalists are the worst because the live only with those who think the same way and so have their beliefs constantly validated rather than challenged.
“My parents, family, relations, neighbours, school, friends and peers or the group (cult) I live with have the same belief as me – so it must be right!!” They seldom ask it the other way about - “I have the same belief as everyone I know – why is that?” “I learnt it in school when I was young so it has to be true because there has to be a god”. For some it might be easier to keep the same views as they had as children. To me that lack of thinking is immature.
