You are constantly making analogies you cannot make. You think the meaning of the “RP realm” label is stronger than it actually is. You attempt to “prove” it by making an analogy with a strong label, but that’s circular logic, you are just assuming your conclusion. That’s not proving anything.
The meaning of the label is weak. It’s a meeting point. People don’t have to RP. Again, since you don’t accept any arguments (eg, an analogy with PVP realms where you also did NOT have to PVP, you could have stayed in the city and chatted all day, it was completely within the rules, similarly on PVE realms you did NOT have to PVE), just ask Blizzard. Or do some googling, this was discussed before, I linked an example piece earlier.
