Scripture: Isaiah 44:22, 2 Corinthians 3:17, Ephesians 4:31-32
This doesn't mean I haven't run into Christians concerned about D&D. I have run into a few. This doesn't mean I haven't run into things that I consider incorrect when it comes to Christianity and it's response to D&D. For example, I was in a Catholic bookstore a few years ago and found an examination of conscience from a diocese in Minnesota that lists playing D&D as one of the sins you should confess (the Catholic church has no official stance on D&D, and that particular examination of conscience has been in print in the exact same form since the 80s).
When I was in grade school, my Sunday school did a unit which was originally going to be the "evils" of D&D, at which point I went to our teachers and asked if I could run a session of D&D in front of the class so they could actually see what the game looked like. They agreed, so long as they got to examine the books beforehand. I loaned them my D&D Basic and Expert set, and I got the green light.
In the end, a group of adventurers traveled up a river and fought a giant crocodile, and the cleric healed the party members after the fight. The teachers concluded that while some people might abuse the game, in the sense of it being damaging to their spiritual health, it didn't appear to be something intrinsically bad or without merit.
That said, as an adult, years into adulthood, I've run into anti-D&D bias not from organized religion, but from pop culture references. My wife's friend was concerned that I played D&D because she remembered all of the talk shows and psychologists that went on daytime television to explain how the game made people disassociate from reality.
This very night, watching an episode of Forensic Files, one of the police they talked to regarding a specific case mentioned that a vampire obsessed guy that killed a woman also happened to play D&D and "we've found that many of the kinds of people that commit murders like this play that game."
It's not Christianity that was the bad guy, or is the bad guy. It's people that don't understand something that looks "weird" from the outside looking in, not understanding that thing and not knowing anyone that will admit to being involved in tabletop gaming, and assuming that "weird" thing must be bad, because they don't grasp it and nobody they know (or think they know) can defend or explain the hobby.
The problem from the gamer side out is exacerbated by the something else. I'm going to say right now that I fully respect anyone's journey to higher understanding, and while I may wish it weren't so, if someone comes to the point to where they do not believe there is a greater power in the universe, I respect that it is something intrinsic to them, and I trust that they have reasoned and contemplated on their own to reach that conclusion.
That said, atheism has become "cool" for a lot of geek culture folks, and when something is cool, rather than just a fact of what you believe, it is a lot easier to fall into the same kind of tribalism that some Christians also fall into. Thus we have a lot of virulently anti-Christian comments that marginalize Christian gamers, and often these are people that will seize upon the early 80s as an example that proves their point, that "they" are against "us," without fully reconciling that some of "them" are "us."
In the end, I think this is again a microcosm of the same problem we have in society as a whole. People form tribes, and people that disagree with them end up being the enemy, instead of just people that don't agree with us, communication stops, and everybody starts living an in echo chamber where they convince themselves of what reality seems to be instead of what it is.
