Not that I have a problem with swearing, but the purpose of swearwords are to be offensive. That is the whole point behind them.
And they're fun to use because of that. Its nearly a tragedy that they're being devalued so much today.
I find that swear words, like what draugur are more to emphasize something. The entire Offensive part of it is more to do with the context that it is being used in. Like the word Nigger I can see why people take offense in it but sometimes its not meant to be an offense yet people will be offended.
