Just have it. When, where and why will be made clear as you go along.
I suggest you see what forum you are in, as some allow a light banter, some less so, some allow "contentious argument that is intended to support a specific position via attacks on a contrary position. Polemics are mostly seen in arguments about controversial topics." (Thanks, Father)
Various forums have their rules. It took a lot for me to look which forum I was posting within.
As some forums you need permission to let fly.
Stick around, post, play and you'll learn.
It's only black and blue with usually no blood on the floor.
