RDR2 is totally just cosplaying as a cowboy! And honestly how different is paintball and call of duty? I'd say sure, they're different in their medium, but in an identical fantasy. They're trying for the same thing in different ways, but it's all just playing army.
And for the record, I've always liked playing cowboy and playing army.
We'll the Torah does not include the new testament, all the Jesus bits, I think that's probably what he's getting at.
And I don't think we need to pretend that the Bible has one consistent message all the way through anyway. There are dozens (or more) examples of pretty major contradictions in the bible. That clarifying question of "god or Jesus said that?" Is really not a crazy question.
