I don't want to jump in the discussion, but I just want to say this:
Only an obscene person will condemn obscenity. For example
children accept swearing as a natural language, but adults condemn it because
their own obscenity is greater than that of children. The jovial
man-about-town with a stock of obscene stories will sternly reprove his son
for talking about excrement. The untruthful mother will spank her child for
lying. I have seen a man, with pipe in mouth, whipping his son for smoking. I
have heard a man say as he hit his son of twelve, "I'll teach you to swear,
you little bastard." When I remonstrated, he said glibly, "It's different
when I curse. He’s just a kid."
So, I guess, to start to talk about one's obscene things and condemn it,
means "mental offtopic", not formal offtopic.
Some people changes their values in time, some not. We write a text messages
here; so, even if one said rude words sometimes, however, after while he/she
may already "forget what he said" (but the messages with obscene words are
still availabe to see, and not available to edit). But maybe that's not so
important thing to pay your attention at? If you start to condemn it, then
you fix the interest over it, and pass the actual problems.
