No, I dont think so, but I have been DM’d by one or two people who weren’t participating in the discussion, they were reading or just following along; my (and other similarly minded folks in said discussion) arguments apparently got them to at least somewhat reconsider what they believed. It was only ever a handful of times over the years, but I think it still fits the premise of your question.

Now granted, this was mostly on like 2010’s “Christian creationist verses basically all of science” rage-bate Facebook groups (as was the style at the time). I have no way of confirming these people were being genuine, but also no real reason to doubt them. Most of the messages I got were people learning for the first time that Evolutionary Theory wasn’t “anti-Christian.” That the vast majority of Christians and Christian denominations weren’t actually Young Earth Creationist or necessarily against the concept of the theoretical foundations of academic biology. Heck, one or two of them didn’t even know that the overwhelming majority of Chritstians are not biblical literalists. They had been taught that most of the fields of science were basically a (insert boogeyman here) plot to destroy Christianity or god or something.

Again, these weren’t the people I was “debating” but rather just curious onlookers watching me, an insufferable 20-something edgy-atheist (again, as was the style at the time), dunk on people who had absolutely no intention of doing anything other than move the goal post to protect sky daddy.
