What skill is essential for critiquing or supporting an argument within writing?

The skill of defending an argument is essential for critiquing or supporting a position within writing because it involves articulating reasons and evidence to back up a claim. When you defend an argument, you engage with opposing viewpoints, challenge counterarguments, and provide justification for your stance. This process deepens understanding and analysis, clearly outlining the strengths of the argument being made.

Additionally, defending an argument requires critical thinking, as it involves evaluating the validity of your points and considering how they resonate with or refute alternative perspectives. Just presenting information or summarizing an argument does not engage with the core aspects of critique and support, which are integral to effective discourse. Thus, the ability to defend is crucial in reinforcing convictions and evaluating the merit of different viewpoints in writing.
