A little mini-rant here. Bear down...
Words are funny things. They can be powerful tools to build and inform, and they can also tear down and destroy.
Here's the deal with curse words. I'm actually not against them for the most part, believe it or not. I use them, probably more often than I should. They are not bad things in and of themselves. But there is definitely a time and a place for them. Saying something like, "If I have to try and beat Sephiroth one more 'damn' time..." is fine. That's what the word is there for, to express frustration. Even Pixar has put the word "hell" into G-rated movies (Cars & Ratatouille), because it beautifully summed up how a character was attempting to express themselves. Used correctly and cleverly, cursing is not a bad thing.
On the other hand: those who feel the need to curse every other word to make a point. Perhaps they think they're coming off as more grown-up or edgy. They're not. They come across as immature, careless, and not putting real thought into the issue. Cursing to express yourself offends me not so much because it's offensive as it's just plain lazy. Make a point if you must, but if you drop the f-bomb every other word to try and make it, you've pretty much lost, because you've just proven yourself unable to make an argument in a reasonable manner, and it's just not worth the time to pay attention to it.
I think, though, as SilverCrono said, the real issue here is this: if you are disrespecting another editor here at all, stop it. You might use every single one of George Carlin's legendary seven dirty words in the process, or you might use words we'd consider perfectly acceptable in every day language, like "worthless," "stupid," or "terrible". Either way, the goal of the writer is the same when directing them against an individual: you are belittling another person with the goal to make them feel bad about themselves. You are not providing constructive criticism, or telling them what they can do to fix the issue. And while it's slipped through in the past, it has not gone unnoticed. Any editor, any staff member, veteran writer or brand new gnome, should be called on it if it's seen happening. It is there, in black and white, one of the most fundamental rules of the wiki. Disrespect is not tolerated.
