I would say, "I'm offended by the implication that being from a specific location justifies being offensive," but that's not hyperbolic enough to 1. Not be considered serious, and 2. Be something I don't actually somewhat believe.
But if there's one thing I did get from my prudish American upbringing, it's a bit of uncomfortableness about swearing. I tend to only throw them around when I'm angry or annoyed at something. I try to use "balls" or "sack" as expletives more than anything else, though. They generally fit the context better anyway; cunts are resilient, man.
