When someone posts a comment... lets say.. they say.....
I hate cheese!!!
Now 100 forum members might agree with this comment or even laugh at that comment but another 100 might be totally offended by it simply because they love cheese and how dare the poster use the very harsh word HATE when describing cheese. Both sides are right to have their own opinion on it. Both sides agree to disagree with each other about it etc and more importantly niether side gets punished for it. The problem only arises when the 201st person reads this comment who just so happens to be a moderator. They have the power to take action for or against this comment depending on their own personal take on it. Unfortunately if that moderator is a cheese lover they will agree that this comment is in fact offensive to cheese and there is every chance that the original poster is getting an infraction for using the word HATE against cheese.
And all because they hate cheese and you don't.
