The Cambridge Online Dictionary defines rant:
To speak or shout in a loud, uncontrolled or angry way, often saying confused or silly things.
Not one part of that definition has ever applied here with the possible exception of silly, which is often a matter of opinion. One man’s silly can be another man’s sage, and that’s particularly true where politics is concerned.
But speaking or shouting in a loud, uncontrolled, angry way? Of course, this is written, but one can shout in print. Look at the comments on Yahoo or HuffPost stories.
There is no shouting on The Unseen Moon. There is no anger, and it’s certainly not uncontrolled. What I do here at times is political polemics.
The Cambridge Online Dictionary defines polemic:
A piece of writing or a speech in which a person strongly attacks or defends a particular opinion, person, idea or set of beliefs.
Sounds about right. So when you see something here that you strongly disagree with, curse (to yourself) the polemic, but don’t call it a rant.
For most, the definition of rant is simply an opinion one does not agree with.
Sadly and destructively, there is ranting all over the internet.
But not here, brother. Never here.
