When I first came to this BBS I was friendly and nice as I am in real life with real people - quickly I learned it was kinda pointless on the net as people were very rude and easily upset by the slightest thing and attack you just as easily with prearragenged stereotype arguments and classifications - there is a distinct lack of subtlety in these discussions. So I just developed from there and the grunherz bbs character is the result, the point being to upset these other characters as best I can if need be.
In person it's much easier to discuss differences as the exchange and reconciliation of arguments is much more fluid and natural. Not to mention there is not the same pressure to conform your thoughts and perceptions to the sterotype expected behavior- ie grun is right winger or Karnak is left winger so we gotta fight etc.
So yea while I personally am more conservative I'm certainly not the evil grunherz charcater in real life..
