[quote=@Oliver]So what I'm basically trying to ask is, should I dumb myself down for the sake of not annoying the older and more socially advanced members of RPG, or is there a way for me to RP with older people without getting on their nerves?[/quote]

Short answer: No.
Long answer: That depends entirely on your own needs and views. The fact that you're asking this question at all shows me that you really kinda don't wanna dumb yourself down. If you want to be accepted by everyone and everything then yes, you could dumb yourself down. If you want to write stories and roleplay, then no. There's not much else to this question I think.
