No it's not a deflection. Classless or not, words don't bother me, and I don't want the marketplace of ideas to be diminished to conform to the delicate sensibilities of some yokel who gets the vapors if they happen to run across a "bad word" or two.
It's a sliding scale, no? I live on a farm and after my other job I actually use the words in question (and more) with practiced and applied familiarity that far exceeds the capabilities of mere mortals such as some posting here. They are swear words and have a place; I'm not offended. But I wouldn't call the two most commonly used words essential to a marketplace of ideas, and I don't think we should reduce every single descriptive in our communication to the same pointless words.
