In the end it is all just a matter of taste, education and breeding. So there is really no wrong way. The problem is only that some people like it this way and others like the other. Have fun!
People of all kinds of educational levels swear. It has more to do with someone's emotional state and for a smaller part a person's social environment. It's a myth that only uneducated people swear, but I'm sure you've meant to say it's not civilized.
But it still only stresses how swearing is never meant to make a point or explain an argument, but only to ventilate an emotion. Perhaps people underestimate the purpose of swearing.
To be honest, that's why I think some people can hold a grudge against someone for decades and think of normal language as being insulting when it's not meant that way.
Here the case was obvious and the moderators actions were just, and people still start a thread about it. I think that's odd at best.
