I have to agree with you @alignment. It kind of is this way with just about everything. Everything is right and it's wrong. The sad part is so many now days butcher the English language to where slang words are being added to the dictionary to make their language acceptable, rather than have them use their words correctly.
I admit I swear and I am very sarcastic. I do it to be silly mostly I don't berate or belittle someone with the words I choose. I can strip someone down with using regular language and not using any sarcasm or colorful language if need be. To me the 'intelligence' of it all boils down of knowing when and if it should be used. I think using swear words all of the time shows a lack of vocabulary so to me it doesn't mean you're any more intelligent than anyone else just lazy.
My sarcasm it to the point of someone will say "Can you spell that?" Instinct answer is "Yes I can, but would I? I don't think so." or 'Could you spell that for me? T - H - A - T . Yeah, I'm bad LOL
