Your genetic/family connections are the most important thing you have on this Earth, mother and father being the most important of all of those, but your siblings will be there most or all of your life. Compared to that, some belief system, among the millions of such systems that have come and gone is not much. Be humble, like my hero Kwai Chang Kane. When he's asked his opinion of someone's belief he says, "who is to say it is not so?"

I believe Mennonites shun. If so it's really hard and you are the one that has to live with the consequences. I was a JW and when I left I was shunned by everyone I knew except my Mom and she stuck with me till her death.

It took me a long time to tell my mom I was an atheist she looked at me like I was joking and changed the subject. It’s never come up again. My close friends know and are accepting. I think family sees what they want to see no matter what you tell them until they are ready or it’s forced on them. I’m not inclined to do that.

tricky do you have an otherwise good relationship and want to remain in their lives? everyone lies about something if at the end of the day it would mean very little to keep up a deception of faith then i see little to be gained and potentially much to be lost good luck

I think if I were you, I'd lay low as long as possible. Don't live a lie. Live your truth. Just don't talk about it to people who would not understand it.

Let it ride for now but if they ever confront you, tell them the truth. We have a nice Mennonite bakery in the town I work in. I like their bread and deli.

Without knowing the relationship you have with your parents, it is hard to suggest anything. The folks on hear that say don't live a lie. Fuck'em. I guarantee 99% of them have not told their parents everything about their lives.
