Well I guess im fairly confrontational on here, and i'd say i'm the same in real life.
Hell, monday just gone I lamped a guy twice over a stupid issue, long story however.
If theres a point to be made, i'l make it... if someones invading my personal space I'l sort it out. I'm not scared of taking a beating however... so I guess that explains why I'l get in peoples faces if they are being hostile towards me. This is probably due to taking 2 beatings (I say beatings, I was jumped both times) in as many years.
Most situations can be resolved if you have the right attitude. If your confident.. I find majority of people will step down straight away.
