There is, which is why there's a point in there about reference RL religion in D&D's fantasy... D&D has arguably been disrespectful to a whole range or religions, that way, from major ones in the early days (trivializing biblical miracles, faux-Satanism), to myriad others with Deities & Demigods, Druid and Witch classes, and the like. To increasingly scrubbing the game of such from 2e on.
That doesn't sound horrible. But it could've been done without, I suppose, if sticking to only fictional (and, hey, TM-able) deities headed off any RL issues, however fringe they might've seemed to developers when considering that appendix.
Oddly, though, that doesn't seem to be the main thrust of Yaarel's point, I'm not sure I /do/ see it, it seems like just 1e gets a pass, for reasons that don't stand out as uniquely applying to 1e, but 5e doesn't. Which is troubling to me, because most of the time Yaarel has some interesting ideas and perspectives, including some that touch on magic & religion in ways that seem downright enthusiastic about modeling RL magical practices or beliefs in D&D, while this complaint does seem actively hostile to such modeling.
(And, OTOOH, y'know, the hobby has seen games like In Nomine….)
