In my personal opinion: Yes, However not in a cosmetic aspect, What ever speech pattern you may have, How well you are at spelling, your grammar, These are not things that should define someone as a 'Bad Roleplayer' To me, The right way is being aware of others you are playing with, Keeping in mind that it is a game, (Although it is perfectly fine to have a serious roleplay, as long as your relationship with the other players isn't broken up by, something your character said, or did.) Never putting your character before another's character, after all, In Roleplay there is no "Main" character, everyone is as important as the next person, I don't think it's right to try and kill off another's character unless they want that. Another thing, Don't try to control someone else, Pressure them to do something they disagree with doing, Some people do not have the willpower to resist such demands and end up doing things they regret.
And all this is just my opinion, but if you ask me, even those who may not understand Roleplay as you do, Always give them a chance, they may not become like you, but if you can have an understanding, That is something. To me it's important to be communitive with the other players, To be honest, make your feelings known, Try to get them to understand you, and try to understand them. But always remember, Some are new to Roleplay, Some have been doing it for years. But people can always change. They can always learn new things they never thought about before. And some may thing it is fruitless to talk to those who have their differences, But you can always learn from each other.
