Tell them if they don't lay off, you're gonna baptize them in blood.

Ideally you would establish boundaries in a way that's gracious and helps them to learn something about what behavior is acceptable and what isn't. But that's a long shot for most of us. So I think the place to start is with "boundaries". Everybody has certain rights to protect a bit of personal territory, and religion is one of those areas. Your family does not have a right to force you to listen to their views, to question your views, etc. That kind of conversation is something that is very personal, and you have a right to choose whether or not to engage in it. So that's an example of where you might draw a boundary: "this is my business, not yours". Now it's a matter of training your family that the boundary is there, and that you're not a pushover regarding that boundary. Again, it's nice to train them gently if you can, but make no mistake -- if firmness is required, you should use it. Most people will get the message fairly easily, but some are more stubborn than others and you may have to turn up the volume. I prefer to let people know with the minimum force which will get the job done. So restraining yourself from overreacting can be a challenge. Bear in mind that it takes some time, but is usually effective. If you really end up with someone who just doesn't get the message, you may have to consider whether you're willing to have that person in your life at all.

I am very spiritul but I do not do religion. I do not go for the Jesus thing. I dont have anything against anyone that does, its just not for me. I live in the bible belt and have been told I am going to hell etc etc. When people start up with me I just tell them that I am glad it works for them but it does not work for me. What I am doing is what IS working for me and I am sorry if they cant understand that but that is the way it is. Then if they keep on I tell them I am not going to argue with them. And if I have to I will walk away. Over and over if need be. They finally get the picture usually. But NEVER show any weakness about it to them, if you do they will never let you alone.

Don't make the mistake of saying you don't believe it. That is a triple dog dare to them to try and change your mind. Instead say things like "I'm happy that your faith brings you so much joy. I have my own beliefs, thank you". Or "Uncle Bob let's talk about something else". If that doesn't work then you have a bigger problem then them pushing religion. Sometimes removing yourself from their presence is all that you can do.

Get a glass of Ipecac, salt water, or other emetic. As they sit and talk with you about religion, each time they say "Jesus", "Our Lord", "Savior" or "God", discretely take a sip from the glass. After a few minutes you will puke, but be sure it goes all over them. Apologize profusely and ask them to explain about religion some more. Repeat as necessary.

dont think you can, its really up to your parents if they decide or ever decide to stop. You have to understand that every culture is different and most of our parents are brought up conservative and more traditional rather.

just kinda pretend to go along with it until you are 18... then you can step out of their territory and practice your own.
