"Now, I don't want to get off on a rant here..."People ranting about their political opinions, religious beliefs or similar usually don't intend to be entertaining. Some, however, have realized that serious messages can't be distinguished from parodies anyway — so why not make the most of it? And thus, some comedians, propagandists, and other characters chose to present their opinions with a lot of attitude, making rants designed to be entertaining while still communicating a serious message. Not to be confused with The Rant, the writer's comments alongside a webcomic.
