While I would think at least 50% of the population (plus, additionally only me, apparently), would find use of the word cun* offensive, I'm betting most of them wouldn't find use of the word "darned" offensive. But I've been wrong on numerous occasions in my life.
Or, if you're referring to the word "redskins", I think you have to think about context. A guy insulting a guy by referring to him as a female body part is more derogatory than referring to a team as "redskins", imo.
I find it funny that James Ford is all upset about a word being used in a thread whose very title is more offensive and he hasn't complained about that yet. Come on the NFL Landover team is super offensive. Lets change that first and maybe the bad karma will go away.
