That's unrealistic. This is a message board. Arguing and ranting and raving comes with the territory. It's basic human nature.
As an analogy, look at your common house cat. If you take any small object and make jerky movements with it in front of a cat, it will either try to swat it or pounce on it. The reason is that they are hard wired that way. I don't know if it is even possible to train a cat to not do that.
It's the same with message boards. There are always some people who are going to respond to combative language. And to a certain extent, it can be claimed that arguing is one of the main purposes of message boards.
From a personal perspective, I try hard to not post things that are insulting towards others. I don't see any harm in a little spoofing, but I try to make it a rule to not post anything that I wouldn't say in person to the people to whom I am responding. However, that's just my personal choice. I don't expect everyone else to do things the way I choose to do them.
