When I swear, there's no way I would want a child to hear it. Their parents would hate having to explain what I said and they would dread their children repeating it in front of 'polite company'.
I wouldn't want my mother to hear it, because her brain would explode thinking that she created a son who, some 20+ years on his own, could create the thoughts behind my swearing.
My father would probably just pause for a second, chuckle, and then utter a string of such vile filth that I couldn't look at a roll of duct tape again without nausea.
I think the core message of the post is a really, really weak version of what Louis CK got into regarding the "n-word".[1] Without saying something offensive, you're still putting that offensive thing into the person's mind. If you write "fvck", you know people are reading it as "fuck". It's just cowardly.
