Anger Management experts have a saying: "The only thing between you and the unemployment line is one angry shit taken on the boss's desk."
Which is to say, getting pissed off at the wrong time can ruin our life. But stopping a good rage once it starts is sometimes like trying to reverse a lava flow by farting it back up the volcano. This is especially true on the internet, where a lack of consequences mean "anger management" isn't even a thing. People often won't bother to email or comment unless something pissed them off (this is why I don't read article comments, here or anywhere) and once they do, they feel the need to crank up the anger to 10.
