anon you can argue till the cows come home but rp is a collaborative effort where not everyone is here to be your character's happy pump so you can do whatever you want consequence free and some people actually endeavor to create an enjoyable rp experience for both parties.

so yeah you want to play the bitchy and crass character? don't cry when it gets old and people are tired of your shit cause you don't know when to rein it in because "well ackshually that's just what my character would do." some people don't like characters that do stuff like that. if it bothers you so much try finding a different hobby that's all about your needs and not about the collaborative experience.
