Counterclaims support an argument by providing an opposing viewpoint that can be addressed and refuted. This helps to strengthen the argument by showing that the author has considered all sides of the issue and has a well-reasoned response to the counterclaim. By addressing and refuting counterclaims, the author can demonstrate the validity of their argument and provide a more convincing argument overall.
