Yes, I've seen this same drama in one form or another posted on the message board many times. Grown-ups don't have to consult other people to see if it meets with their approval before deciding what they believe. Things that are not anyone else's business do not have to be explained to anyone; it's personal and private. Atheists are not obligated to discuss their personal opinions with antagonists, but if someone has chosen to tell people about their atheist views then they should also be prepared to defend them.
If theists don't want to go down "a sad dark road" why do they get in their cars and drive themselves to church to have their fears enhanced every Sunday" That's what keeps them hanging on to their security blankets and pacifiers. How is someone's atheism dragging theist relatives anywhere when the theists are the one's making all the demands? Atheists are not obligated to "drag" anyone into anything like theists are instructed to do. Atheists have decided for themselves not to support deception, whether its self-deception or someone else's deception, because they have concluded that it is unethical to support unsubstantiated claims. Unlike theists who think that everyone wants to know what they believe; atheists usually keep their personal private opinions to themselves, and that is not lying. All an atheist would ever tell anyone is to look for the answers themselves, because people who have never asked any questions sure can't answer yours.
Family members have no more right to intrude into other family members private affairs with rude inquiries than anyone else does. If a relative who was not mentally handicapped; called me to inform me that they didn't respect my ability to make my own decisions, and obviously they wanted to make them for me, I would not be the one crying when I hung up the phone. It's very handy to learn how to say, "I can't talk to you right now because I'm busy", that's what I do with people who are rude enough to try and run other people's lives.
