I believe it’s a because the author specifically uses you, which calls the audience to act. hope this helped!
To make a strong argument, the writer or speaker must avoid logical fallacies.
This is because a fallacy is something that is untrue, thus if it was logical your reader might be persuaded against your argument. Basically, as a writer you don't want to contradict yourself and you only want to support one side of an argument.
Hope this helps! :)
