I have to say I find it really, really annoying, and infuriating. Finally I know how I made other people feel when I was a JW.
Our youngest son has warned his in laws to not bring it up with us. Both of his wife's parents are pastors. It must kill them to keep quiet but they do. When we first met them about 6 years ago, we were pretty newly out of the JW's and they thought they had found some fresh meat and the mother, especially, kept preaching "Jesus this" and "Jesus that" until I wanted to strangle her. My son is very sensitive to my moods, and caught on that I was about to blow and stopped her. There hasn't been a problem since.
Our other daughter in law is a very involved Christian, but she is respectful of us, and only talks about what she is doing at church, not what they preach.
I consider myself to be a spiritual person, but I am NOT religious, and am totally and completely turned OFF by any organized religion. So they had better leave me alone. I will be polite at first and just tell them I don't discuss religion, but if they persist, I might lose my cool, my maturity, and my dignity. It's a strong issue with me.
I completely respect a person's choice to be involved in a church, and if it makes them happy and works for them, all the better. Just don't try to get me involved too. I'm perfectly happy, thank you, not being in a church or group.
