That video pretty much sums it up.
I remember reading a book by Jeremy Clarkson (it wasn't mine I was bored and my mate who I was staying with had it on his shelf) I can't remember what it was called now (mmm yummy meds) but he wrote a section about arguing on the internet.
He said how the argument, due to it being faceless, went on and on for hours and hours. In public however? you have the "don't feel like being punched in the face" limiter. Basically he mentioned how he got into an argument in his local pub thinking that his intellect would win the day. He got biffed in the face :lol:
I've always tried my utmost to act on a forum how I act in real life. People who have met me via the internet will attest to this, and have pointed out just how shocked they were that the person they knew on the net immediately (no instant shyness or anything like that) became the person they were standing in front of.
I'll admit that many years ago I did have my run ins and ding dongs but not usually because I wanted them. It was usually people slagging off my software (I used to program emulated gambling machines, a nasty world to be in tbh).
