I'm sorry, but you have no idea what you're talking about. You may not find it offensive. That doesn't make it inoffensive.
Try looking at it from someone else's shoes. Sure, my little brother doesn't understand when people call him that, he's too young. But I understand, and I'll tell you what, the people who use the term bloody well know what it means.
That being said, I am sick and tired of every special interest group (and those are growing exponentially daily) being offended by something. PC has run amok and it's running our country. Case in point is Iraq, were we can't properly respond with enough force in fear of offending the islmao-fascists who want us all DEAD.
I grew up using the term and until this thread had no idea of it's 'history'. So here's one person who's used the term and didn't know what it meant.
