People should sometimes take a moment to consider what the impact of their RP design has on the real-world players.
There is a virtually unlimited number of ideas to chose from when creating a character's personality; expecting a person to put up with your RP because it isn't really you might be more than you have the right to ask of your friends.
Can you imagine sitting at a table with a group of black friends and pretending you are a slave trader? Sitting with a group of Jewish friends and pretending you are a Nazi?
It is your right to RP as you like, but perhaps you want to think of a new personae.
