Yea I never got why religious people think god damn is bad, it's a recognition of god's existence paired with a recognition of damnation, something bad happens and you go "god damn" which compares the bad thing that happened to a damnation from god, I'd understand it's bad if it was "damn god" instead of "god damn".
When I watched Pulp Fiction as a teenager I never got it when Travolta and Jackson were in the car and Travolta kept saying "god damn it" and Jackson got pissed off at him for saying it.
"Taking the lord's name in vein" explanation is strange, cause to me it means "talking about god carelessly", so shouldn't that make any mention of god on a TV show "in vein"? I mean just shouting "God!" when someone is surprised or shocked or laughing isn't in vein? Just trying to wrap my head around it, not that it matters cause I don't say god damn anyway, I like dagnabbit
