I'm afraid that won't do, Mr. GoGettter. In order to drive this point home, I'm afraid a single example isn't enough. You're going to need to provide enough examples to establish a pattern, and demonstrate that profanity can be singled out as the sole source of laziness.

Otherwise, you're just talking out of your fat, lazy ass.

6. It shows a lack of intelligence and/or creativity.

This is complete and utter horseshit. I don't even know what it's supposed to mean.

Every time you write a word or a sentence, you are rejecting an infinite number of words or sentences you could have used in its place. There are no true synonyms. Every word or combination of words carries its own connotations in a given context. As a writer, it's your job to choose the words and combinations of words which most closely paint a picture in the reader's mind. If some of those words happen to be the ones which society has arbitrarily deemed "bad", so be it.

By the logic of this argument, you could say the same thing about any word in any sentence ever written.

In the recently released Critical Failures IV: The Phantom Pinas, a character says, "Randy, you already done shit in the chili."

This wasn't the result of me crapping out the first thing that popped into my head and saying "Fuck it. That's good enough." There are other ways I could have had this character express that Randy had been the catalyst of a situation which was now beyond his control. Hell, I could have said that very thing, but it wouldn't have been true to the character. She isn't the type to say "catalyst of a situation."

I could have gone with, "Randy, you already done scrambled that egg.", but I felt the phrase I chose instead more accurately reflected the character's personality and upbringing.

Comparing those two metaphors, "shit in the chili" is objectively more creative, because "You can't unscramble an egg" is a much more known saying. This would still be the case if the word "shit" were replaced with "poop" or "defecate", which tells us that the vulgarity of the word "shit" is not a means with which to measure the writer's creativity. And your inability to come up with a competent counter-argument lends credit to the writer's intelligence.

5. Because Jesus or some shit.

Naturally, my research into the topic landed me on some Bible-thumping websites, a lot of which liked to quote James 5:12

But above all, my brothers, do not swear, either by heaven or by earth or by any other oath, but let your “yes” be yes and your “no” be no, so that you may not fall under condemnation.

There are two problems with that argument. The first is that "swearing" in this case, has nothing to do with using "bad" words. This is about literally taking an oath, which makes the Bible an odd choice of text for people to swear oaths on.
