When unintelligent people fight back because the don't like other peoples ideas, they often have to result to measures like name calling
and emotional statements like "HOW CAN YOU SAY THAT!", as well as your said critism of chosen words.
Less intelligent people get taught a certain way to think and certain ideas to believe when they are young. Then when they are challenged by more intelligent people later in life, unable to provide reasons why the intelligent people are wrong they attack them in any manner they can. Often, this results in the said name calling and word critisism.
When more intelligent people get critisised for their ideas, they work out why they are right (or realise they're not), and defend their ideas with their own valid points. As opposed to looking for stupid things like whats wrong with the post or what names they can call the critics.
This forum has brought me to realise this. You watch a heated debate thread progress and you often see the more intelligent people making valid points, and the idiots starting to use labels.
Thats my insight anyway
