For me, the first person to swear, or has to use insulting language loses the argument.
I disagree.
If you're having some kind of good-natured intellectual debate then fair enough, but in an argument swearing can be ace. Dropping the occasional f-bomb for emphasis works a treat if you slap it next to a very valid point.
But just swearing and doing little else is indeed a clear white flag.
