So of course I don't believe it was random in any way, and I also was kind of happy to talk to the because I want to see how far off they are from the "real history" of the church.
Anyway... I told them right off the bat after our small talk that I am happy to talk to them, but I also have a laundry list of issues with the church and if they want to continue discussing it they would have to answer those for me. I made clear that I was not looking to harm their personal testimonies, but that as I've researched the history I have found so many things that I do not believe are real...
The missionaries said they wanted to talk to me more and see if they can guide me back to the church. I told them I have been so much more happy and comfortable with myself since I left, but that I am happy to talk to them if they really want to go down that road.
My wife is aware they stopped by (we have a Ring doorbell so she could even watch the whole conversation if she wanted to... and might have done already), but I have no idea what her thoughts are as far as talking to them again.
Anyway... anyone else ever deal with this? I was polite and did not even really tell them they were wrong. I asked them to explain the translation process to me and they said "Do you mean how he used the ancient glasses to translate the plates?" to which I said that was one of my deal breakers with the church since that's not what happened (but did not go into details). I also asked about polyandry and they said there are good answers about that but we would need to discuss it another time since they needed to get to an appt.
Just curious what people thought- I have no problem talking to them about my issues to see what they would answer with, but I also know that they will have no idea about this stuff and as much as I want more LDS people to know the truth, I actually feel bad unloading this info on missionaries... even though they keep telling me they want me to.

TLDR; Missionaries want to come and talk to me about coming back, and even though I told them I have no interest in coming back I'd be happy to talk to them about my issues. They say they want to do that, but I feel bad basically unloading a ton of church history on them that they clearly do not know about. I feel bad talking to them, but since I warned them 3-4 times and they still want to... I kind of want to see what answers they have.
