I don't know if anyone would actively get mad-mad at you, but if you're worried about it, you can always do what I did and roll a Qestir since I have no idea how to do any of the RPing stuff at all. If you're not talking and only doing emotes or custom /em, you're being lore-friendly without having to stress over whether you're doing it right. Bonus that no one in the RP areas is going to really question you lurking around and spectating because they know you're not supposed to talk anyway!
