I was apart of the situation yesterday and most of my characters would be considered racist due their backstory with slave trading and other situations they have been in.
So depending on the person you run into or meet only the way they can be a racist. We play in zombie apocalypse. People change over time due to what happened to them.
So if it's trolly then of course it should be reported and be dealt with the admins and the other staff members who are dealing with it.
The town we were in yesterday, Stary or what we used to call Tortuga, When it was a hotspot last year that was ran by mygroup, mine the Common Folk and the Hassan, Eagle and Louie group the Black fangs who owned the town. It was a bandit town so all sort of People and characters where there with a server wait of 53 man wait. And the people there that was racist and it amazing due the town and the situation we were in due the outbreak.
But again myself I wouldn't change how I roleplay my character, if the admins and owners change the rules for then I would other than that I wouldn't.
But I understand where your coming from, and it's always good to ask questions about things if unsure I always do and I admire people who go out and ask and get the voice heard.
