You can chance losing any friendship you want, but when she and her ilk begin expecting or demanding that you and yours pretend the same thing, that’s no friend.

After rereading that a couple times and looking through the comments I would have to agree with best without gods just be there if she needs you. Of course fernapple had a good point too.

I would not take it upon myself to expose anyone to my truth. I would offer suggestions that might lead a person to a greater knowing (in my opinion), but I would not use force! Mainly, because I can’t envision it working.

I think it would be very disruptive to a person's psyche if they were a person of faith all their lives and you managed to somehow convince them that they were wrong. If you ever did it, it should at least be done gradually.

I'd say dont' try to copnvince, but just state the truth(s) over time.

If a question is hypothetical and painfully stupid, would I have the right to show the OP the painful truth? Asking for a friend.

As was once said, but unfortunately I cannot remember who said it, "Truth is always a painful thing to hear, especially to those who never want to hear it, BUT Truth, no matter how painful does far less harm than fiction does."
Hence, always be honest and truthful because the pain it may cause will often diminish but the lies will live on for ever.

Depends on your goal. Done correctly, it could rid the world of fruitless pursuits, charlatans and layers of deceit. But for some this is the barrier between contentment and a nihilistic nightmare. I find it difficult to prove a null hypothesis. I wonder how that would come to pass.

You cannot give the truth away but people are willing to pay double for a fantasy

Thanks to everyone who responded to this question. I did get what I think are some good insights from your comments.

it maybe depends upon how you are defining "God?"
plus you have posited conditions that cannot possibly arise, so what is the point, if i may ask

Christian beliefs and practices infringe on the rights of others. When their churches don't pay taxes you have to pay more to cover their lack of paying taxes. They want to stop your right to an abortion...your right to contraception ....and your right to watch pornography.

I think the best course of action is to plant an idea, and let a person's curiosity run with it...or not. They have the burden of finding out themselves.....but then again didn't a snake do that once regarding a bit of fruit?

Proof = Believing factual evidence.

Faith = Believing what you've been told regardless of the factual evidence.

Good luck with that...
