The use of swear words is not necessarily an indication of ignorance. In fact, it could be said that those who state this are unable to find any other means of 'putting down' and sensibly criticising anothers statements. It can be an attempt on their behalf to show themselves as a more intelligent being, one that has no need to lower themselves to such standards.
Get real...we all do it and sometimes it just feels good.
Happy days
