I don't actually have that much experience with that kind of situation, but I believe the "border" gets broken mostly due to a lack of communication. If it just happens out of the blue, the other person might feel like you're doing it simply because you don't like them. I'm pretty sure I know what incident you're talking about, and I don't quite recall if there was any discussion about it. It's too easy to see yourself in your character and and up getting offended when someone doesn't like them. Correct me if I'm wrong about this.
Well at first, I had assumed that it wouldn't go anywhere since nothing had been said OoC, and so hopefully it was just between the two characters. Then it was inferred that my character had acted unreasonably, and I just couldn't accept that. Maybe it would mean nothing to someone else, but I can't roleplay well when I neither understand nor accept how something has developed, and things as they are, I'm not entirely unconvinced the character hasn't been written off as some kindof monster (and by more than one person) just for using strong language. That's why, for me, it's become more than just a disagreement between two characters.
More than anything, I'm exasperated that I've managed to land myself in this position again, since I feel like I've been here too many times to count. So much so I had a feeling it would end up this way before it happened, really.
