I find out that the born again christians are the best in brainwashing their children with dumb fairy tale?

... beliefs.. I was with my dumb friend last night who start praying for the food before we eat and I was holding the piece of bread when they start doing it. I got shocked and wait holiding the bread untill they finish their prayers because I never saw it comming. Then they start preaching me abt the end of the world will come very soon and I must find happiness in their chirch and other all the christians are dumb including Catholics,Protestent , Evangelical, Eglashies, Penthakostha ect .also they have a shuttle service to carry me to their chirch every sunday free of charge and they are planing to build born again schools in every country..and my friend believe the world is only 6000 years old and evolution is a man written myth. ( god help those school children )They have two kids who are around 10 or 12 ..I feel sorry for those kids.. what should I do?
