You know what does offend me? People who think they can just define what kind of person I am by sticking me in a bunch of categories like "never offended," or "cute when he doesn't comb his hair," or "best Mafia player ever." You can't fit this star polyhedron in a square hole.
I actually get offended after several attacks. Earlier I didn't even mind it. I started minding it when I got vios for doing it. So why should I allow others to abuse me. I shrugged off many racial attacks. I still shrug it off. But if a player doesn't stop and is doing it to antagonise me, then I report it.
